Testing before commissioning It is recommended that after receiving a new oscilloscope, a check of the unit is carried out as follows:
1. check if the unit has been damaged during transport. If you find that the cardboard packaging or the protective foam pads are badly damaged, save them until the entire unit and its accessories have passed the electrical and mechanical test. 2. checking the accessories The accessories supplied are described in Appendix B “Accessories” of this manual. Check the accessories against this description to ensure they are complete. If any accessories are missing or damaged, please contact your dealer. 3. checking the unit If you notice any damage to the exterior of the unit or if the unit does not function properly or does not pass the performance test, please contact your dealer. If the unit has been damaged during transport, please keep the outer packaging and also inform your dealer about the damage. Function test Check the proper functioning of the meter as follows 1. connect the mains cable to a power source. Switch on the unit with the mains switch ” “. The unit performs a self-test and displays the PeakTech logo. First press the Utility button and then the H1 button to access the Function menu. Select “Calibrate” using the multi-rotary knob and press the H3 button to select “Factory Set”. The default value for the probe attenuation in the menu is 10X. Set an attenuation of 10x on the probe and connect the probe to the CH1 socket. Align the slot on the probe with the BNC connector of channel 1 and turn the probe clockwise to secure it. Connect the probe tip and earth terminal to the plug of the task head compensator. 3. press the “Autoset” button. The square wave signal with a frequency of 1 KHz and a 5V SS value is displayed after a few seconds
– 12 –

Probe compensation When you connect the probe to an input channel for the first time, you must adapt the probe to the input channel. An uncompensated or incorrectly compensated probe will result in measurement errors. Perform the probe compensation as follows:
1. Set the damping factor of the probe to 10X in the menu, also set the switch on the probe to 10X and connect the probe to channel 1. When using the hook tip, make sure that it remains securely connected to the probe. Connect the probe tip to the signal connector of the probe compensator and connect the clamp of the reference cable to the earth terminal of the probe compensator; then press the AUTOSET button.
2. Check the displayed waveforms and adjust the probe until correct compensation is achieved
Overcompensated Correct compensationUndercompensated 3. Repeat the process if necessary to obtain the most uniform image possible.
– 13 –

Setting the probe damping factor
The probe has several probe damping factors that affect the vertical scaling factor of the oscilloscope.
If the set probe attenuation factor is to be changed or checked, press the function menu key for the respective channel and then the selection key corresponding to the probe until the correct value is displayed.
This setting remains valid until it is changed again.
Note: The damping factor of the probe in the menu is preset to 10X at the factory.
Make sure that the value set on the attenuation switch of the probe corresponds to the attenuation value set on the oscilloscope.
The values that can be set with the switch on the probe are 1 X and 10X (see picture).

Note: When the

attenuator switch is set to 1X, the

probe limits the bandwidth of the oscilloscope to 5 MHz. You must set the switch to 10X if you

want to use the entire bandwidth of the oscilloscope.

Safety instructions for the use of the scanner head
The handle protection ring around the probe handle prevents it from accidentally reaching over or slipping off and thus from touching the possibly live metal parts (see Fehler! Verweisquelle konnte nicht gefunden werden.. )

Handle protection Warning: To avoid electric shock, always keep your fingers behind the safety protection ring of the probe. To protect you from electric shock, do not touch any conductive metal parts of the probe tip when it is connected to a power source. Before taking any measurements, always connect the probe to the oscilloscope first and then connect the earth terminal to the housing of the DUT.
– 14 –

Self-calibration With the auto-calibration, the oscilloscope can be quickly set to the optimum state for highly accurate measurements. You can run this programme at any time, but you must do so if the ambient temperature varies by more than 5°C. Remove all probes and cables from the input sockets before performing the auto-calibration. Press the “UTILITY” button, then the “H1” button to enter the FUNCTION menu; turn the “Multipurpose” knob to select “Adjust”. Press the “H2” menu selection button to access the “Selfcal” option and start the programme after confirming “OK” that all settings are correct.
Introduction to the vertical system
The following picture shows the buttons and keys for the VERTICAL CONTROL. The following exercises will familiarise you with the vertical control step by step.

1. With the rotary knob

“VERTICAL POSITION” you can

display the signal in the

centre of the waveform window. With

the

“VERTICAL

POSITION” adjustment knob, you set

the vertical display position of the signal. Turning the “VERTICAL POSITION” adjustment knob moves

the pointer of the channel’s zero position up and down, following the waveform.

Measurement capabilities
If DC coupling is set for the channel, you can quickly measure the DC component of the signal by observing the difference between waveform and signal ground.
If AC coupling is set for the channel, the DC component is filtered out. This mode helps you to display the AC component of the signal with higher sensitivity.

FFT function
The FFT (Fast Fourier Transformation) function converts a time-based waveform into its individual frequency components. This function can be very useful in evaluating the input signals. You can match these obtained frequencies with known system frequencies from system clocks, oscillators or voltage supplies, for example. In the audio range, the FFT function splits any waveform into its individual components and thus shows the composition of a sound and the distance ratios of the individual tones in the frequency band, as well as the average levels. Example- Activate and use the FFT function: 1. Press the Math button to display the maths function menu. The mathematical waveform (blue) is
displayed. 2. Select FFT from the bottom menu. 3. Select Source in the right- hand menu; select for channel 1. 4. Select Window from the right-hand menu and choose a useful window type (see table). 5. Select Format in Vrms or dB. 6. Select Hori in the right-hand menu; press the menu function several times to display the symbol above
or below this menu item. This allows you to change the time base of the FFT wave with the multi-controller depending on the horizontal position. 7. Select Vertical in the right menu; press the menu function several times to display the symbol above or below this menu item. This allows you to change the voltage/division or zero line of the FFT wave with the multi-controller depending on the position.

Select FFT window

There are six FFT windows. Each window makes trade-offs between frequency resolution and amplitude accuracy. Choose the window based on what you want to measure and the characteristics of your source signal. The following table will help you choose the best window:

Art

Characteristics

Windows

Rectangle (Rectangle)
Hanning

This window is best for frequency resolutions, but is the worst for accurately measuring the amplitude of these frequencies. It is the best window for measuring the frequency spectrum of nonrepetitive signals and measuring frequency components near DC.
Use the rectangular window for measuring transients or peaks where the signal level before and after the event is almost the same.
Also usable for sine waves with the same amplitude and with fixed frequencies
Broadband noise with relatively slowly varying spectrum. This window is well suited for measuring amplitude accuracy, but less so for frequency resolutions.
Use the Hanning window to measure sine, periodic and narrowband noise.

Best suited for transients or peaks where the signal levels before and after the event differ significantly.

Hamming

This is a very good window for frequency resolution with slightly better amplitude accuracy than the rectangular window. It has a slightly better frequency resolution than the Hanning window.
Use the Hamming window to measure sine, periodic and narrowband noise.

Blackman

Best suited for transients or peaks where the signal levels before and after the event differ significantly.
This is the best window for measuring the amplitude of frequencies, but offers the poorest frequency resolution. Use the Blackman-Harris window for single frequency signals
and finding higher order harmonics.

Bartlett

The Bartlett window is a slightly narrower version of the triangular windows, with “zero weight” at both ends.

Emperor

The frequency resolution when using the Kaiser window is adequate, the spectral leakage and amplitude accuracy are both good.
The Kaiser window is best when the frequencies are very close but have very different amplitudes (the sidelobe level and form factor are close to the traditional Gaussian RBE). This window is also good for the random signals.

Notes for FFT use The waveform zoom function also works for FFT. Use the dBV RMS scale for a detailed view of multiple frequencies, even if they have different amplitudes.
Use the linear RMS scale to compare all frequencies in an overall view. Signals that contain a DC component or offset can lead to incorrect FFT signal amplitude values. To
minimise the DC component for the source signal, select AC coupling. To reduce noise and aliasing in repetitive or single measurement waveforms, set the oscilloscope’s
acquisition mode to average. Nyquist frequency: The highest frequency that an oscilloscope that digitises in real time can measure is equal to half the sampling rate and is called the Nyquist frequency. If not enough sampling points are acquired and the frequency is higher than the Nyquist frequency, the phenomenon of the “false waveform” occurs. Therefore, pay more attention to the relationship between the sampled and measured frequency. Using VERTICAL POSITION and VOLTS/DIV knobs 1. Use the VERTICAL POSITION knob to change the vertical position of the waveforms of all channels
(including those created by mathematical calculation). The resolution of this adjustment knob changes with the vertical division.
2. Use the VOLTS/DIV adjustment knob to set the vertical resolution of the waveforms of all channels (including those created by mathematical calculation), which determines the sensitivity of the vertical division in the order 1-2-5. The vertical sensitivity increases when you turn the adjustment knob clockwise and decreases when you turn it counterclockwise.
– 32 –

Set horizontal system The HORIZONTAL CONTROLS consist of the HORIZ-MENU button and adjustment knobs such as HORIZONTAL POSITION and SEC/DIV. 1. adjustment knob HORIZONTAL POSITION: with this adjustment knob you control the horizontal
positions of all channels (including those created by mathematical calculation) whose resolution changes with the time base. 2. setting knob SEC/DIV: with this you set the horizontal scale factor with which you determine the main time base or window. 3. key HORIZ Menu: Press this key to display the operating menu on the screen. Enlarge waveform (zoom) Press the HOR button and the display splits in the middle. The upper half of the display shows the main window and the lower half shows the zoom window. The zoom window is a magnified area of the main window.
When Main Window is selected in the bottom menu, Horizontal Position and SEC / DIV are used to adjust the horizontal position and time base of the main window. The time base of the zoom window is also changed.
When Zoom Window is selected in the bottom menu, the Horizontal Position and SEC / DIV are used to adjust the horizontal position and time base of the zoom window. Hint: If the time base of the zoom window is the same as in the main window, the interface is automatically switched back to normal mode and the zoom mode is switched off. You can also zoom in on the waveform using the touch screen, as described in the associated chapter.

Set trigger system
The trigger determines when the oscilloscope starts acquiring data and displaying the waveform. Once set correctly, the trigger can convert a fluctuating display into a meaningful waveform.
When the oscilloscope starts acquiring data, it records enough data to display the waveform to the left of the trigger point. The oscilloscope continues to record data while waiting for a trigger condition. When a trigger is detected, the unit continuously records enough data to display the waveform to the right of the trigger point.
The trigger control area consists of a 1 rotary knob and 2 menu buttons.

TRIG LEVEL: This knob sets the trigger level. When you press the knob, the level is reset to zero.

Force:

Press this button to create a trigger signal. This function is primarily used with the trigger modes “Normal” and “Single”.

Trigger Menu: The button calls up the trigger control menu.

Single trigger
Trigger control
The unit provides four types of triggers: single trigger, alt trigger, logic trigger and bus trigger. Each trigger type has different submenus. There are two ways to get into trigger mode: Key operation: Press Menu in the trigger field to open the trigger menu. With H1 you can then select the extended trigger menu, which you can scroll (turn) and select (press) with the multipurpose knob. Touch screen operation: Press the house icon to open the touch menu. Select Trig Menu and then the trigger (Single, Alt, Logic, Bus) in the lower menu. The trigger type can then be selected in the right-hand screen menu under Type.

XY Mode: XY mode is used to display the amplitude from one waveform against the amplitude from another. The data point from the first waveform sets the horizontal position, while the corresponding data point from the second waveform shows the vertical position for each point. The oscilloscope is in untriggered sampling mode: the data is displayed as bright dots. How to use the knobs and buttons: The Vertical Scale and Vertical POSITION adjustment knobs for Channel 1 are used to adjust the
horizontal scale and position of the yellow waveform. The Vertical Scale and Vertical POSITION adjustment knobs for channel 2 are used to adjust the vertical
scale and position of the blue waveform.
