When the modulation depth is greater than 100%, envelop distortion will occur.
This should be avoided in actual circuit. At this time, the output of the
instrument will not exceed 5 Vpp (the load is 50 Ω).
The query returns an integer ranging from 0 to 120.
:MOD:AM 80 /*Sets the AM modulation depth of GI to 80%.*/
:MOD:AM? /*The query returns 80.*/

[:SOURce[<n>]]:MOD:AM:INTernal:FREQuency <frequency>
[:SOURce[<n>]]:MOD:AM:INTernal:FREQuency?
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency <frequency>
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency?
Sets or queries the modulating waveform frequency of AM or FM of the specified
function/arbitrary waveform generator channel.
When omitted, by default, the
operations are carried out on
GI.
You can send the [:SOURce[<n>]]:MOD:TYPE command to set the modulation type.
AM: Amplitude Modulation. The amplitude of the carrier waveform changes with the
amplitude of the modulating waveform.
FM: Frequency Modulation. The frequency of the carrier waveform changes with the
modulating waveform.
You can select Sine, Square, Triangle, or Noise as the modulating waveforms.
The query returns an integer ranging from 1 Hz to 50 kHz.
:MOD:AM:INTernal:FREQuency 100 /*Sets the modulating waveform frequency of AM of
GI to 100 Hz.*/
:MOD:AM:INTernal:FREQuency? /*The query returns 100.*/
