MODULATIONSMODUS

The PSG9080 can output modulated waveforms in single or dual channels. Modulation is the process of processing the information from the signal source and adding it to the carrier to make it suitable for channel transmission. It is the technology that changes the carrier with the signal. The carrier wave can be a sine wave, square wave, pulse wave, arbitrary wave (except DC signal wave). The modulated wave can be from an internal modulation source or an external modulation source. Modulation types supported by PSG9080 include AM, FM, PM, ASK, PSK, FSK, pulse, and burst.
Select the modulation mode:
Press MOD and then → Type now you can select the desired modulation mode with the menu buttons or the rotary knob.
Select carrier waveforms:
Press Sharp and use the rotary knob to select the desired carrier waveform. The different settings of several parameters of the carrier waveforms (such as frequency, amplitude, offset, etc.) affect the output of the modulated waveform. For different carrier waveforms, the adjustable range of each carrier parameter is also different (in relation to the model of instrument you are using and the selected carrier waveform, see “Specifications” for details). For the setting method of the carrier parameters, please refer to the corresponding introduction in the section “Basic Output Waveform”.
Selecting the source:
The PSG9080 can accept modulation waveforms from internal or external modulation sources.
Press Source to select “Internal” or “External” modulation source.
Internal source:
After selecting the internal modulation source, press the Sharp menu button to select sinewave, square wave, triangle wave, ascending exponential, descending exponential, or anwave as the modulation source. The default is a sine wave.
External source:
When the external modulation source is selected, the signal generator accepts the external modulation signal input via the MOD connector on the front panel. The frequency range of the external signal is 0~20kHz, and the amplitude range is -5V~+5V.
Setting the carrier frequency:
After using the modulation source “Internal”, press the menu key Carr. F to set the carrier frequency. Use the numeric keyboard or the direction keys and the rotary knob to enter the desired frequency value. The frequency range is 0.001 Hz to 1 MHz and the default is 500 Hz.
Setting the modulation wave frequency:
After using the “internal” modulation source, press the menu key Mod.F to set the frequency of the modulated wave. Use the numeric keyboard or the direction keys and the rotary knob to enter the desired frequency value. The modulation frequency range is from 0.001 Hz to 1 MHz and the default is 500 Hz.
AM
Amplitude modulation is a modulation method in which the amplitude of the carrier wave changes according to the desired transmission signal, but the frequency remains unchanged. Setting the modulation depth: The modulation depth indicates the degree of amplitude change, expressed as a percentage.
The range of the amplitude modulation depth can be set from 0% to 200%. Press the menu button Depth to set the amplitude modulation degree.
FM
Frequency modulation is a modulation method that changes the carrier frequency according to the modulation signal. The magnitude of the frequency change of the modulated wave is determined by the magnitude of the modulation signal, and the period of the change is determined by the frequency of the modulation signal.
Set the frequency deviation:
Frequency deviation refers to the deviation of the frequency of the modulation waveform relative to the carrier frequency. Press the menu key FM.Dev to
set the FM frequency deviation.
PM
Phase modulation is a modulation method in which the deviation of the carrier phase from its reference phase changes proportionally to the instantaneous value of the modulation signal.
Adjust the phase deviation of the modulation wave:
Phase deviation refers to the change in phase of the modulated waveform relative to the carrier phase. Press the menu key PM.Dev to adjust the phase
deviation of the phase modulation. Use the numeric keyboard or the direction keys and the rotary knob to enter the desired deviation value. The adjustment
range of the phase deviation is 0°to 359.9°, and the default value is 180°.
ASK
The modulation method that uses the digital baseband signal to control the amplitude variation of the carrier wave is called Amplitude Shift Keying (ASK),
also known as digital amplitude modulation.
Setting the polarity:
Press the Polar menu button to select the amplitude of the modulated wave controlled by “positive polarity” or “negative polarity”.
Setting the ASK amplitude:
Press the Ample menu button to set the ASK amplitude. Use the numeric keyboard or the direction keys and the rotary knob to enter the desired amplitude value. The ASK amplitude range is 0%-200%, the default is 80%.
FSK
The modulation method used to control the change in carrier frequency is called frequency shift keying (FSK).
Set the polarity:
Press the Polar menu button to select the amplitude of the modulated wave controlled by “Positive Polarity” or “Negative Polarity”.
Set the hop frequency:
Press the menu button Hop. F to set the hop frequency. Use the numeric keyboard or the direction keys and the rotary knob to enter the desired frequency value.
PSK
Phase-shift keying (PSK): With phase-shift keying, the phase of the output signal is shifted by the set phase, depending on the logic level of the source signal.
Setting the polarity:
Press the Polar menu key to select the amplitude of the modulated wave controlled by “positive polarity” or “negative polarity”. If the polarity is set to “positive polarity”, a high level at the source signal shifts the output sig­nal by the set phase. If the polarity is “negative”, the phase of the output signal is shifted at a low level.
Setting the phase:
Press the Phase menu button to set the PSK phase. Use the numeric keyboard or direction keys and the rotary knob to enter the desired fre­quency value. The PSK phase range is 0″ to359.9°.
PWM
Digital adjustment of the pulse width and pulse period time of the pulse wave can be achie­ved, which is more accurate than setting the duty cycle. The pulse modulated waveform can only be a square wave. This method varies the ratio of the on-time to the specified period du­ration.
Set the wave inversion:
When you press the W.Inv menu button, you can select Normal and Inv. to control the out­put.
Set the pulse width:
Press the menu key Width to set the pulse width. Use the numeric keypad or the direction keys and the rotary knob to enter the desired value (the unit can be us, ms, s). The pulse width range is 0.001us to 4s, and the default is 0.100us.
Set the pulse period:
Press the Period menu button to set the pulse duration. Use the numeric keypad or the direction keys and the rotary knob to enter the desired fre­quency value. The period length range is from 0.001us to 40s, and the default is 10.00us.
