INSTRUMENT FUNCTIONS
This section provides information about the basic functionality and the user interface.
CHANGING CENTER FREQUENCY AND SPAN
Tab Frequency key ( ) or Frequency Information box to adjust the center frequency and Span (X-scale) of the spectrum measurement.
CHANGE REFERENCE LEVEL
Tab Amplitude key ( ) or press Amplitude Information box to adjust the amplitude (Y-scale) of the spectrum measurement. CHANGING SWEEP MODE
Tab Sweep key ( ) or press Sweep Information box to adjust the sweep mode of the spectrum measurement.
CHANGING BANDWIDTH
Tab Bandwidth key ( ) or press Bandwidth Information box to adjust the RBW, VBW of the spectrum measurement. SET UP TRIGGERING
Tab trace key ( ) or press Trigger Information box to set up triggering. Trigger menu does not appear in normal operation mode. It can be controlled in zero span.The spectrum analyzer provides the following Trigger modes.

• Free Run:
  A sweep is automatically updated internally. After the last sweep, the next sweep is performed.

• External:
  A sweep is triggered by an external TTL signal applied to the ‘Trig In’ port.

• Video:
  A sweep begins when the input signal passes the trigger level. Video trigger is useful for analyzintransient signal.

• Periodic timer :
  A sweep runs periodically according to the Trigger Peri Time.

• RF Burst:
  A sweep begins when the signal in the IF stage crosses the Trigger Level.

ADDING TRACE
Tab Trace key ( ) or press Trace Information box to add traces of the spectrum measurement.
How to activate trace(s):

1.  Select Trace (from T1 to T6).
2. Select Trace Property (Clear Write, Max Hold, Min Hold, View (Capture), Average).
3. Turn Trace On.

The spectrum analyzer provides the following trace modes.

• Clear/Write:
  In its default state, the spectrum analyzer overwrites the trace after each sweep. You can apply all detectors in this mode.

• Average:
  The trace is the result of the moving average over several sweeps. The spectrum analyzer calculates the (moving) average of the power levels for each pixel over a particular number of sweeps in the range from 1 to 10,000. Averaging reduces the effects of noise but has no effects on sine signals. Using the trace averaging therefore is an effective way to detect signals in the vicinity of noise.

• Max Hold:
  The trace shows the maximum power levels that have been measured at each pixel. To overwrite a max hold trace, change a parameter in a way that the results cannot be compared any more (e.g. the span). Using the max hold trace mode is an effective way to detect intermittent signals or the maximum values of fluctuating signals, for example.

• Min Hold:
  The trace shows the minimum power levels that have been measured at each pixel. To overwrite a min hold trace, change a parameter in a way that the results cannot be compared any more (e.g. the span). Using the min hold trace mode is an effective way to highlight signals within noise or suppress intermittent signals.

• View:
  The view trace mode freezes the current trace and aborts the measurement. Using the view trace mode is an effective way to evaluate the trace, for example with markers.

ADDING MARKER

Tab Marker key ( ) or tab Marker Shortcut – Peak Search ( ) to set markers on the spectrum measurement. The marker is placed on the trace move marker position using finger (click and drag). When Marker is enabled, Marker Table will be displayed on the bottom of the measure result with the corresponding frequency and amplitude information. The spectrum analyzer supports 6 markers, five of which can be used as either markers or delta markers.

• Delta:
  Delta marker level is always a relative to the main marker level and so the delta marker level unit is always dB. The delta marker frequency is always relative to the main marker. The delta marker frequency is the frequency difference between the frequency at the point marked by the main marker and the frequency at the point marked by the delta marker.

• Delta pair:
  Delta pair marker level is always a relative to the main marker level but it also changes by the signal level. The delta pair marker frequency is the frequency difference between the frequency at the point marked by the main marker and the frequency at the point marked by the delta pair marker.
  **** Deactivating marker(s)
  If you delete marker 1 (M1), all delta markers that are relative to that marker are also deleted.

Peak Search:

1.  Tab Marker Shortcut – Peak Search ( )
2.  Select Marker Property or
3. Set Marker to Center / Start / Stop

Always peak can be set using Peak Track On.

MOVING MARKER

Tab and drag on the marker bar or icon to change the marker position in the trace window.

MARKER FUNCTION
In addition to the frequency and level readout, the spectrum analyzer provides two additional marker functions in spectrum analyzer mode.

• Noise Marker:
  The marker noise function calculates the noise power density at the marker position in dBm/Hz. This involves with the several variables in the calculation of the noise power density, including the trace pixel values, the resolution bandwidth, the detector, and the level display mode (absolute or relative).

• Frequency Count:
  The frequency counter accurately measures the frequency at the marker position. When calculating the horizontal position of the marker, the spectrum analyzer includes the current span, center frequency and the frequency of the pixel the marker is on. As the trace only has 801 pixels, the marker position is just an approximation, especially if the span is very wide.
  With the frequency counter, however, you can get a more accurate result of the horizontal marker position.

CONFIGURING MEASUREMENT

Measure Setup key ( ) provides all available configurations (required settings) of the current selected measurements. Configurable items may differ from the different measurements. Configurable items that show specifics for each operating mode or measurement are provided in the corresponding sections of this guide.
Measure key ( ) provides all available measurements (supported measurement) of the current selected mode. Available measurements may differ from the different modes. Available measurements that show specifics for each operating mode or measurement are provided in the corresponding sections of this guide.

SPECTRUM ANALYZER MODE

The default operating mode of the spectrum analyzer is the spectrum analyzer. The spectrum analyzer provides the functionality to perform measurements in the frequency domain, e.g. to identify the power and frequency of signals.
Gated Sweep option available under Sweep ( ) function key provides time-domain measurement of a particular frequency over time. The span during time domain measurements (Gated Sweep mode) is zero (zero span). You can use Gated Sweep measurements to monitor the characteristics of a time-varying signal.
To perform a time domain measurement, you have to set the span to zero or go to Gated Sweep mode manually by setting Gated Delay and Gate Length per signal to be captured. When the Gated Sweep is On, the horizontal axis is time, and the vertical axis shows the signal levels (refer to Gated Sweep Mode for the detail).
SCREEN LAYOUT AND ELEMENTS
The following illustrates the screen layout in spectrum analyzer mode. It shows all elements that are the same for all operating modes of the spectrum analyzer. Screen layouts that show specifics for each operating mode or measurement are provided in the corresponding sections of this guide.

SETTING FREQUENCY AND SPAN
The center frequency represents the frequency at the center of the horizontal axis in the measurement result window.
The span is the frequency range around the center frequency that a spectrum analyzer displays on the measurement result screen.

1. Tab the Frequency key.
2. Select the “Center Freq” softkey.
3.  Enter the center frequency in an open field. The frequency you have entered becomes the new center frequency.
4. Select the “Span” softkey.
5. Enter the span frequency in an open field. The span you have entered becomes the new span frequency.

SETTING START AND STOP FREQUENCY
Defining a start and a stop frequency is best suited for example, for measurements on harmonics or signals whose exact frequency is unknown.

1. Tab the Frequency key .
2. Select the “Start Freq” softkey.
3. Enter the start frequency in an open field.
4. Set a stop frequency with the “Stop Freq” softkey.
5. Enter the stop frequency in an open field. The stop frequency you have entered becomes the new stop frequency.

** If you have entered a stop frequency that is outside the maximum frequency range of the instrument, then the spectrum analyzer sets the stop frequency to the possible maximum.
Zero Span mode
You can also activate time domain measurements by selecting Zero Span. When measuring in the zero-span mode (time domain), the span is 0 Hz. In that state, the spectrum analyzer measures the signal at the current center frequency only. Instead of displaying the spectrum, the spectrum analyzer shows the signal power over a certain time period. The horizontal axis becomes the time axis. The display always starts at 0 s and stops after the currently set sweep time.
SETTING REFERENCE LEVEL
** The reference level is represented graphically by the grid line at the top of the measurement result window. The reference level sets the input signal gain up to the display stage. If the reference level is low, the gain is high. That means that even weak signals are displayed clearly.
If you are measuring strong signals, you have to set a high reference level to prevent an overload of the signal path of the analyzer and to keep the signal within the display range. If you are measuring the spectrum of a composite signal, make sure that the  eference level is high enough to cover all signals and that all signals are within the amplitude range of measurement result window.

1. Tab the Amplitude key.
2. Select the “Ref Level” softkey.
3.  Enter the reference level in an open field.
4. If you change the reference level, the spectrum analyzer adjusts the position of the trace as you make the changes.

SETTING ATTENUATION
RF attenuation adjusts the input range inside the analyzer. It is coupled directly to the reference level. If you have set a high reference level, RF attenuation is turned on so that the input mixer always remains in the linear range.

1. Tab the Amplitude key.
2. Select the “Attenuation” softkey.
3.  Enter the attenuation level in an open field (0 to 48 dB in 4 dB step).
4. If you change the attenuation, the spectrum analyzer adjusts the position of the trace as you make the changes.

USING PREAMPLIFIER
To increase the input sensitivity, you can turn on internal pre-amplifier provides an ~20 dB gain. In the default state of the spectrum analyzer, the preamplifier is turned off. If you want to measure signals with low powers, you can turn it on.

1. Tab the Amplitude key.
2.  Turn On and Off the “Preamp”.

SETTING RESOLUTION BANDWIDTHS
The resolution bandwidth in a spectrum analyzer determines the frequency resolution for frequency domain measurements and therefore determines how well it can separate adjacent frequencies. The measurement result observed depends on the passband of a resolution filter.
In the default state, the resolution bandwidth is coupled to the span, i.e. if you change the span, the spectrum analyzer adjusts the resolution bandwidth.

1. Tab the Bandwidth key. By default, the resolution bandwidth is coupled to the span.
2. Select the “Manual RBW” softkey.
3. Enter the resolution bandwidth in an open field. The spectrum analyzer uses the resolution bandwidth you have entered for the measurement.
4. Select the “Auto RBW” softkey to again couple the resolution bandwidth to the span.

The spectrum analyzer has resolution bandwidths from 1 Hz to 5 MHz in a 1-3-10 sequence.

** Automatic adjustment of the sweep time
In its default mode, the spectrum analyzer automatically adjusts the sweep time as soon as you change the resolution bandwidth. This adjustment makes sure that the settling time required for the selected resolution filter is carefully considered.
SETTING VIDEO BANDWIDTH
** The video bandwidth (VBW) basically smoothes the trace by reducing the noise and therefore making power levels easier to see. The noise reduction is a result of the video filter. This lowpass filter defines the video bandwidth and filters the higher frequency parts of the voltage from the signal.
Like the resolution bandwidth, the video bandwidth has an effect on sweep speed. Before each measurement, the video filter has to settle.

1.  Tab the Bandwidth key. By default, the resolution bandwidth is coupled to the span.
2.  Select the “Manual VBW” softkey.
3. Enter the video bandwidth in an open field. The spectrum analyzer uses the video bandwidth you have entered for the measurement.
4. Select the “Auto VBW” softkey again to couple the video bandwidth to the RBW.

The spectrum analyzer has video bandwidths from 1 Hz to 5 MHz in a 1-3-10 sequence.
SETTING DETECTOR
The number of measurement results collected in a single sweep usually is extremely high, especially if the span is large. However, the display of the spectrum analyzer can display only 801 results in horizontal direction, as it is limited by the number of pixels that are available on the display. Therefore, it has to combine measurement results to fit them on the display. In that case, one pixel represents a frequency range = span /801.
The detector determines the way the spectrum analyzer combines and displays the results for one pixel. The data base is the video voltage of the analyzer.

1. Tab the Trace key.
2. Select the “Detector” softkey.
3. Select the detector from the submenu. If the “Auto Detector” selection is active, the selection of the trace detector is always “Normal.”

The spectrum analyzer provides several types of detectors.

• Positive Peak:
  If the positive peak detector is active, the spectrum analyzer displays both the maximum power levels that were measured in the frequency range covered by a pixel.

• Negative Peak:
  The min peak detector displays sine signals with the correct level and suppresses noise. Therefore it is useful to find sine signals in the vicinity of noise.

• Sample:
  If the sample detector is active, the spectrum analyzer shows one random power level that was measured in the frequency range covered by a pixel. The sample detector is useful for measurements in the time domain (span = 0 Hz) as it provides the only way to represent the timing of the video signal correctly.
  In the frequency domain, the sample detector is an effective way to measure noise power because noise usually has a uniform spectrum with a normal amplitude distribution. Signals may get lost if you are using the sample detector for measurements with a span that is greater than “RBW x 801”.

• RMS:
  If the RMS detector is active, the spectrum analyzer measures the spectral power over one pixel. The RMS detector is best for measurements on digitally modulated signals because it provides stable and true power readings. In combination with a high sweep time, you can increase the display stability even more because the measurement time for each pixel increases. Noise measurements also provide stable results if you apply the RMS detector in combination with a high sweep time.

GATED SWEEP MODE

Tab Sweep key ( ) and select the Gated Sweep ( ) to configure Gated Sweep mode. Gated sweep allows you to synchronize the measurement sweep with an event so that the analyzer collects data at the appropriate time. This is useful for measuring signals in the time domain such as pulsed RF, time multiplexed, or burst modulated signals.
**  Gated Sweep
Gated Sweep mode is only available on instrument with Gated Sweep option installed. CONFIGURING MEASUREMENT**

Measure key ( ) provides all available measurements (supported measurement) of the spectrum analyzer mode.

MEASURING CHANNEL POWER
The channel power measurement selectively measures the power of modulated signals. Unlike a power meter that performs measurements over its entire frequency range, the channel power measurement measures the power of a specific transmission channel. Other signals in the frequency spectrum do not show in the results. It determines the total power of the channel by integrating the results on the trace.
The following parameters need to be configured to perform channel power measurement using Measure Setup key ( ):

• Channel Bandwidth to be measured.

MEASURING OCCUPIED BANDWIDTH
The occupied bandwidth is defined as the bandwidth that contains a specified percentage of the entire power of the transmitter. Numerous standards require an occupied bandwidth of 99 which is also the default setting. If you need another percentage for the occupied bandwidth, you can set values from 10 % to 99.9 %.
The following parameters need to be configured to perform channel power measurement using Measure Setup key ( ):

•  Channel Bandwidth to be measured.
•  Occupied Bandwidth in %.
  

MEASURING SPECTRUM EMISSION MASK (SEM)
The Spectrum Emission Mask (SEM) measurement is a method to detect spurious emissions or intermodulation products of a signal. When performing a SEM measurement, the spectrum analyzer checks the signal against a spectral mask to see whether the signal complies with a specific standard or not. Therefore, the spectrum analyzer provides predefined spectrum emission masks for various telecommunications standards.
Spectrum Emission Mask is changed in the Measure Setup menu. ( )
A ‘Selection mask’ includes ‘Cat A,>3GHz’, ‘Cat B,>3GHz’, ‘31<P<38dBm,>3GHz ‘, ‘P<31dBm,>3GHz’ and Custom. Spectrum emission mask is applied when all other items except Custom are selected, and by selecting Custom, the file explorer appears as shown in the figure below.

1.  Select a file.
2. Click “OK” button at the bottom.
3. Confirmation of application of spectrum emission mask.

MEASURING ADJACENT CHANNEL POWER (ACP)
The Adjacent Channel Power (ACP) measurement is a method to measure the power over more than one transmission channel and also evaluate the power of the adjacent (or alternate) channels of the transmission channel. The ACP performs measurements according to a specific channel configuration, e.g. a particular radiocommunications standard.
The following parameters need to be configured to perform channel power measurement usingMeasure Setup key ( ):

• Main Channel Bandwidth to be measured.
•  Adjacent Channel Bandwidth to be measured.
• Alternate Channel Bandwidth to be measured.

**** Selecting the frequency span larger than channel bandwidth (> 10%)
If the frequency span is too large in comparison to the channel bandwidth (or the adjacent-channel bandwidths) being examined, only a few points on the trace are available per channel. This reduces the accuracy of the waveform calculation for the channel filter used, which has a negative effect on the measurement accuracy.
The channel bandwidth must be smaller than the frequency span (span > channel bandwidth)

REALTIME SPECTRUM ANALYZER MODE
A realtime spectrum analyzer is a two-dimensional display that contains a line trace that shows the power levels for each frequency for a particular bandwidth or span with the horizontal and vertical axis representing frequency and amplitude. The significant difference to a conventional spectrum analyzer is the way the realtime spectrum analyzer gets its data.
To enter the realtime mode, tab the Home ( ) key or Mode ( ) key and select the “Realtime Spectrum” softkey in the corresponding menu.

The following measurements are available in realtime spectrum analyzer mode

**** If you have entered a stop frequency that is outside the maximum frequency range of the instrument, then the realtime spectrum analyzer sets the stop frequency to the possible maximum.

SETTING REFERENCE LEVEL
The reference level is represented graphically by the grid line at the top of the measurement result window. The reference level sets the input signal gain up to the display stage. If the reference level is low, the gain is high. That means that even weak signals are displayed clearly.
If you are measuring strong signals, you have to set a high reference level to prevent an overload of the signal path of the analyzer and to keep the signal within the display range. If you are measuring the spectrum of a composite signal, make sure that the reference level is high enough to cover all signals and that all signals are within the amplitude range of measurement result window.

1. Tab the Amplitude key.
2. Select the “Ref Level” softkey.
3.  Enter the reference level in an open field.
4.  If you change the reference level, the realtime time spectrum analyzer adjusts the position of the trace as you make the changes.

SETTING ATTENUATION
RF attenuation adjusts the input range inside the analyzer. It is coupled directly to the reference level. If you have set a high reference level, RF attenuation is turned on so that the input mixer always remains in the linear range.

1. Tab the Amplitude key.
2.  Select the “Attenuation” softkey.
3. Enter the attenuation level in an open field (0 to 48 dB in 4 dB step).
4.  If you change the attenuation, the realtime time spectrum analyzer adjusts the position of the trace as you make the changes.

SETTING DETECTOR
The number of measurement results collected in a single sweep usually is extremely high, especially if the span is large. However, the display of the realtime spectrum analyzer can display only 801 results in horizontal direction, as it is limited by the number of pixels that are available on the display. Therefore, it has to combine measurement results to fit them on the display. In that case, one pixel represents a frequency range = span /801.
The detector determines the way the realtime spectrum analyzer combines and displays the results for one pixel.

1. Tab the Trace key.
2. Select the “Detector” softkey.
3.  Select the detector from the submenu. If the “Auto Detector” selection is active, the selection of the trace detector is always “Normal.”

The Realtime Spectrum Analyzer provides several types of detectors.

• Positive Peak:
  If the positive peak detector is active, the realtime spectrum analyzer displays both the maximum power levels that were measured in the frequency range covered by a pixel.

• Negative Peak:
  The min peak detector displays sine signals with the correct level and suppresses noise. Therefore it is useful to find sine signals in the vicinity of noise.

• Sample:
  If the sample detector is active, the realtime spectrum analyzer shows one random power level that was measured in the frequency range covered by a pixel. The sample detector is useful for measurements in the time domain (span = 0 Hz) as it provides the  nly way to represent the timing of the video signal correctly.
  In the frequency domain, the sample detector is an effective way to measure noise power because noise usually has a uniform spectrum with a normal amplitude distribution. Signals may get lost if you are using the sample detector for measurements with a span that is greater than “RBW x 801”.

• Average:
  If the average detector is active, the realtime spectrum analyzer measures the spectral power over one pixel. The average detector is best for measurements on digitally modulated signals because it provides stable and true power readings. In combination with a high sweep time, you can increase the display stability even more because the measurement time for each pixel increases. Noise measurements also provide stable results if you apply the average detector in combination with a high sweep time.

ADDING MARKER
Tab Marker key ( ) or Tab Marker Shortcut – Peak Search ( ) to set markers on the Realtime spectrum measurement. The marker is placed on the trace move marker position using finger (click and drag). When Marker is enabled, Marker Table will be displayed on the bottom of the measure result with the corresponding frequency and amplitude information.Realtime Spectrum Analyzer supports 6 markers, five of which can be used as either markers or delta markers.

• Delta:
  Delta marker level is always a relative to the main marker level and so the delta marker level unit is always dB. The delta marker frequency is always relative to the main marker. The delta marker frequency is the frequency difference between the frequency at the point marked by the main marker and the frequency at the point marked by the delta marker.

• Delta pair:
  Delta pair marker level is always a relative to the main marker level but it also changes by the signal level. The delta pair marker frequency is the frequency difference between the frequency at the point marked by the main marker and the frequency at the point marked by the delta pair marker.
  **** Deactivating markers
  If you delete marker 1 (M1), all delta markers that are relative to that marker are also deleted.

MOVING MARKER
Tab and drag on the marker bar or icon to change the marker position in the trace window.

MARKER FUNCTION
In addition to the frequency and level readout, the realtime spectrum analyzer provides two additional marker functions in realtime spectrum analyzer mode.

•  Noise Marker:
  The marker noise function calculates the noise power density at the marker position in dBm/Hz.
  This involves with the several variables in the calculation of the noise power density, including the trace pixel values, the resolution bandwidth, the detector, and the level display mode (absolute or relative).

CONFIGURING MEASUREMENT
Measure key (   ) provides all available measurements (supported measurement) of the current selected mode. Available measurements may differ from the different modes.

Measure Setup key ( ) provides all available configurations (required settings) of the real-time spectrum measurements. The following items are available for realtime spectrum analyzer mode.
In Density view, high density is represented by the color at the top of the color bar and low density by the color at the bottom of the color bar.

USING REALTIME SPECTROGRAM
The realtime spectrum analyzer has 3 different displays, Realtime Spectrogram which combines spectrum and spectrogram, Persistent density that is a two- dimensional histogram that shows the statistical frequency of any frequency and level combinations for every pixel on the display (‘hits’ per pixel) with a probability distribution, and Persistent spectrogram which combines persistent density and spectrogram display.

The spectrogram provides an easy way to monitor the changes of a signal’s frequency and amplitude over time. Typically, it is used for measurements in which time is a factor.
A typical application of a spectrogram is the monitoring of telecommunications systems that are based on frequency hopping techniques, e.g. GSM. Using the spectrogram, you can see at a glance whether slots are allocated correctly or not. In addition, the result display also provides information on the time a particular channel is in use. In telecommunications systems that use frequency hopping techniques, you can use the spectrogram to monitor the settling time to a new frequency after the channel switching. USING PERSISTENT DENSITY (HISTROGRAM)
The persistence spectrum is a three-dimensional histogram that shows the statistical frequency of any frequency and level combinations for every pixel on the display (‘hits’ per pixel). In this view, the X-axis represents frequency, the Y-axis represents amplitude and the Z-axis represents number of hits. This view therefore displays three-dimensional data on a two-dimensional display, using color to represent the third dimension. Persistent density display of the results the realtime spectrum analyzer shows the trace in twodimensions with the number of hits represented by different shades of color. The result is a trace that covers an area instead of a line trace as you know it from the realtime spectrum result display, for example.
USING PERSISTENT SPECTROGRAM
The persistent spectrogram is a combination of spectrogram which is an easy way to monitor the changes of a signal’s frequency and amplitude over time and persistent density include how frequent a certain level and frequency combination has occurred during the measurement

In combination with a high sweep time, you can increase the display stability even more because the measurement time for each pixel increases. Noise measurements also provide stable results if you apply the Average detector in combination with a high sweep time.

•  RMS:

The RMS detector is best for measurements on digitally modulated signals because it provides stable and true power readings. In combination with a high sweep time, you can increase the display stability even more because the measurement time for each pixel increases. Noise measurements also provide stable results if you apply the RMS detector in combination with a high sweep time.

ADDING TRACE
Tab Trace key ( ) or press Trace Information box to add traces of the LTE-A TDD spectrum measurement.
How to activate trace(s):

1. Select Trace (from T1 to T6).
2. Select Trace Property (Clear Write, Max Hold, Min Hold, View (Capture), Average).
3. Turn Trace On.

The LTE-A TDD analyzer provides the following trace modes.

• Clear/Write:
  In its default state, the LTE-A TDD signal analyzer overwrites the trace after each sweep. You can apply all detectors in this mode.

•  Average:
  The trace is the result of the moving average over several sweeps. The LTE-A TDD analyzer calculates the (moving) average of the power levels for each pixel over a particular number of sweeps in the range from 1 to 10,000. Averaging reduces the effects of noise but has no effects on sine signals. Using the trace averaging therefore is a good way to detect signals in the vicinity of noise.

• Max Hold:
  The trace shows the maximum power levels that have been measured at each pixel. To overwrite a max hold trace, change a parameter in a way that the results cannot be compared any more (e.g. the span). Using the max hold trace mode is a good way to detect intermittent signals or the maximum values of fluctuating signals, for example.

•  Min Hold:
  The trace shows the minimum power levels that have been measured at each pixel. To overwrite a min hold trace, change a parameter in a way that the results cannot be compared any more (e.g. the span). Using the min hold trace mode is a good way to highlight signals within noise or suppress intermittent signals.

• View:
  The view trace mode freezes the current trace and aborts the measurement. Using the view trace mode is a good way to evaluate the trace, for example with markers.

ADDING MARKER
Tab Marker key ( ) or Tab Marker Shortcut – Peak Search ( ) to set markers on the LTE-A TDD spectrum measurement. The marker is placed on the trace move marker position using finger (click and drag).

The LTE-A FDD analyzer provides the following trace modes.

• Clear/Write:
  In its default state, the LTE-A FDD signal analyzer overwrites the trace after each sweep. You can apply all detectors in this mode.

• Average:
  The trace is the result of the moving average over several sweeps. The LTE-A FDD analyzer calculates the (moving) average of the power levels for each pixel over a particular number of sweeps in the range from 1 to 10,000. Averaging reduces the effects of noise but has no effects on sine signals. Using the trace averaging therefore is a good way to detect signals in the vicinity of noise.

• Max Hold:
  The trace shows the maximum power levels that have been measured at each pixel. To overwrite a max hold trace, change a parameter in a way that the results cannot be compared any more (e.g. the span). Using the max hold trace mode is a good way to detect intermittent signals or the maximum values of fluctuating signals, for example.

• Min Hold:
  The trace shows the minimum power levels that have been measured at each pixel. To overwrite a min hold trace, change a parameter in a way that the results cannot be compared any more (e.g. the span). Using the min hold trace mode is a good way to highlight signals within noise or suppress intermittent signals.

• View:
  The view trace mode freezes the current trace and aborts the measurement. Using the view trace mode is a good way to evaluate the trace, for example with markers.

Tab Marker key ( ) or Tab Marker Shortcut – Peak Search ( ) to set markers on the LTE-A FDD spectrum measurement. The marker is placed on the trace move marker position using finger (click and drag). When Marker is enabled, Marker Table will be displayed on the bottom of the measure result with the corresponding frequency and amplitude information.

LTE-A FDD analyzer supports 6 markers, five of which can be used as either markers or delta markers.

• Delta:
  Delta marker level is always a relative to the main marker level and so the delta marker level unit is always dB. The delta marker frequency is always relative to the main marker. The delta marker frequency is the frequency difference between the frequency at the point marked by the main marker and the frequency at the point marked by the delta marker.
  **** Deactivating markers
  If you delete marker 1 (M1), all delta markers that are relative to that marker are also deleted.

MOVING MARKER
Tab and drag on the marker bar or icon to change the marker position in the trace window.

MARKER FUNCTION
In addition to the frequency and level readout, the LTE-A FDD analyzer provides two additional marker functions in spectrum analyzer mode.

• Noise Marker :
  The marker noise function calculates the noise power density at the marker position in dBm/Hz.
  This involves with the several variables in the calculation of the noise power density, including the trace pixel values, the resolution bandwidth, the detector, and the level display mode (absolute or relative).

5GNR SIGNAL ANALYZER MODE
The 5GNR Signal Analyzer Mode is targeted for testing the transmitter of the Base Station according to following 3GPP standards (Release 15).
To enter the 5GNR signal analyzer mode, tab the Home ( ) key or Mode ( ) key and select the “5GNR Signal Analyzer” softkey in the corresponding menu.
The following measurements are available in 5GNR signal analyzer mode:

• RF Analysis (Spectrum, Channel Power, Occupied Bandwidth).
•  Beam Analysis (Multi Beam, Single Beam).

SCREEN LAYOUT AND ELEMENTS
The following illustrates the screen layout in 5GNR signal analyzer mode. It shows all elements that are the same for all operating modes of the 5GNR signal analyzer. Screen layouts that show specifics for each operating mode or measurement are provided in the corresponding sections of this guide.

SETTING CENTER FREQUENCY AND SPAN
The center frequency (channel frequency) represents the frequency at the center of the transmitted channel of the transmitter. The channel center frequency and bandwidth can be set manually. When set to manual band, the ARFCN is unassigned. When a predefined ARFCN is selected, the uplink and downlink carrier frequencies are set automatically.

1. Tab the Frequency key.
2.  Select the “Center Freq” softkey.
3. Enter the center frequency in an open field. The frequency you have entered becomes the new center frequency
   **** Span frequency in 5GNR mode
   In 5GNR mode, span frequency is automatically set by the channel bandwidth. If you select channel bandwidth from bandwidth key, then corresponding span is set automatically (see the table below for span per channel bandwidth)

SETTING REFERENCE LEVEL
The reference level is represented graphically by the grid line at the top of the measurement result window. The reference level sets the input signal gain up to the display stage. If the reference level is low, the gain is high. That means that even weak signals are displayed clearly.
If you are measuring strong signals, you have to set a high reference level to prevent an overload of the signal path of the analyzer and to keep the signal within the display range. If you are measuring the spectrum of a composite signal, make sure that the reference level is high enough to cover all signals and that all signals are within the amplitude range of measurement result window.

1. Tab the Amplitude key.
2.  Select the “Ref Level” softkey.
3. Enter the reference level in an open field.
4.  If you change the reference level, the 5GNR signal analyzer adjusts the position of the trace as you make the changes.

SETTING ATTENUATION
RF attenuation adjusts the input range inside the analyzer. It is coupled directly to the reference level. If you have set a high reference level, RF attenuation is turned on so that the input mixer always remains in the linear range.

1. Tab the Amplitude key.
2. Select the “Attenuation” softkey.
3.  Enter the attenuation level in an open field (0 to 48 dB in 4 dB step).
4.  If you change the attenuation, the 5GNR signal analyzer adjusts the position of the trace as you make the changes.

USING PREAMPLIFIER
To increase the input sensitivity, you can turn on internal pre-amplifier provides an ~20 dB gain. In the default state of the 5GNR signal analyzer, the preamplifier is turned off. If you want to measure signals with low powers, you can turn it on.

1. Tab the Amplitude key.
2.  Turn On and Off the “Preamp”.

SETTING DETECTOR
The number of measurement results collected in a single sweep usually is extremely high, especially if the span is large. However, the display of the 5GNR signal analyzer can display only 801 results in horizontal direction, as it is limited by the number of pixels that are available on the display. Therefore, it has to combine measurement results to fit them on the display. In that case, one pixel represents a frequency range = span /801.
The detector determines the way the 5GNR signal analyzer combines and displays the results for one pixel. The data base is the video voltage of the analyzer.

1. Tab the Trace key.
2.  Select the “Detector” softkey.
3.  Select the detector from the submenu. If the “Auto Detector” selection is active, the selection of the trace detector is always “Normal.”

The 5GNR signal analyzer provides several types of detectors.

• Positive Peak:
  If the positive peak detector is active, the 5GNR signal analyzer displays both the maximum power levels that were measured in the frequency range covered by a pixel.

• Negative Peak:
  The min peak detector displays sine signals with the correct level and suppresses noise. Therefore it is useful to find sine signals in the vicinity of noise.

• Sample:
  If the sample detector is active, the 5GNR signal analyzer shows one random power level that was measured in the frequency range covered by a pixel. The sample detector is useful for measurements in the time domain (span = 0 Hz) as it provides the only way to represent the timing of the video signal correctly.
  In the frequency domain, the sample detector is a good way to measure noise power because noise usually has a uniform spectrum with a normal amplitude distribution. Signals may get lost if you are using the sample detector for measurements with a span that is greater than “RBW x 801”.

• Average Voltage:
  If the Average detector is active, the 5GNR signal analyzer measures the spectral power over one pixel. The Average detector is best for measurements on digitally modulated signals because it provides stable and true power readings. In combination with a high sweep time, you can increase the display stability even more because the measurement time for each pixel increases. Noise measurements also provide stable results if you apply the Average detector in combination with a high sweep time.

•  RMS:
  If the RMS detector is active, the 5GNR signal analyzer measures the spectral power over one pixel. The RMS detector is best for measurements on digitally modulated signals because it provides stable and true power readings. In combination with a high sweep time, you can increase the display stability even more because the measurement time for each pixel increases. Noise measurements also provide stable results if you apply the RMS detector in combination with a high sweep time.

ADDING TRACE
Tab Trace key ( ) or press Trace Information box to add traces of the 5GNR spectrum measurement.
How to activate trace(s):

1. Select Trace (from T1 to T6).
2.  Select Trace Property (Clear Write, Max Hold, Min Hold, View (Capture), Average).
3.  Turn Trace On.

The 5GNR signal analyzer provides the following trace modes.

• Clear/Write:
  In its default state, the 5GNR signal analyzer overwrites the trace after each sweep. You can apply all detectors in this mode.

• Average: The trace is the result of the moving average over several sweeps. The 5GNR signal analyzer calculates the (moving) average of the power levels for each pixel over a particular number of sweeps in the range from 1 to 10,000. Averaging reduces the effects of noise but has no effects on sine signals. Using the trace averaging therefore is a good way to detect signals in the vicinity of noise.

• Max Hold:  The trace shows the maximum power levels that have been measured at each pixel. To overwrite a max hold trace, change a parameter in a way that the results cannot be compared any more (e.g. the span). Using the max hold trace mode is a good way to detect intermittent signals or the maximum values of fluctuating signals, for example.

• Min Hold: The trace shows the minimum power levels that have been measured at each pixel. To overwrite a min hold trace, change a parameter in a way that the results cannot be compared any more (e.g. the span). Using the min hold trace mode is a good way to highlight signals within noise or suppress intermittent signals.

• View: The view trace mode freezes the current trace and aborts the measurement. Using the view trace mode is a good way to evaluate the trace, for example with markers.

ADDING MARKER
Tab Marker key ( ) or Tab Marker Shortcut – Peak Search ( ) to set markers on the 5GNR spectrum measurement. The marker is placed on the trace move marker position using finger (click and drag). When Marker is enabled, Marker Table will be displayed on the bottom of the measure result with the corresponding frequency and amplitude information.

• Delta:
  Delta marker level is always a relative to the main marker level and so the delta marker level unit  is always dB. The delta marker frequency is always relative to the main marker. The delta marker frequency is the frequency difference between the frequency at the point marked by the main marker and the frequency at the point marked by the delta marker.
  Deactivating markers
  If you delete marker 1 (M1), all delta markers that are relative to that marker are also deleted.
  MOVING MARKER
  Tab and drag on the marker bar or icon to change the marker position in the trace window.

MARKER FUNCTION
