 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).
Return
Format
The query returns an integer ranging from 0 to 120.
Example
:MOD:AM 80 /*Sets the AM modulation depth of GI to 80%.*/
:MOD:AM? /*The query returns 80.*/
[:SOURce[<n>]]:MOD:AM:INTernal:FREQuency
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency
Syntax
[: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?
Description
Sets or queries the modulating waveform frequency of AM or FM of the specified
function/arbitrary waveform generator channel.
Parameter

Range
Default
[<n>]
Discrete
{1|2}
When omitted, by default, the
operations are carried out on
GI.
<frequency>
Integer
1 Hz to 50 kHz
1 kHz
Remarks
 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.
Return
Format
The query returns an integer ranging from 1 Hz to 50 kHz.
Example
: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.*/
