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.*/

Syntax
[:SOURce[<n>]]:MOD:AM:INTernal:FUNCtion <wave>
[:SOURce[<n>]]:MOD:AM:INTernal:FUNCtion?
[:SOURce[<n>]]:MOD:FM:INTernal:FUNCtion <wave>
[:SOURce[<n>]]:MOD:FM:INTernal:FUNCtion?
Description
Sets or queries the modulating waveform of AM or FM of the specified function/arbitrary
waveform generator channel.
Parameter
Name
Type
Range
Default
[<n>]
Discrete
{1|2}
When omitted, by default,
the operations are carried
out on GI.
<wave>
Discrete
{SINusoid|SQUare|RAMP|NOISe}
SINusoid
Remarks
 You can select SINusoid (Sine), SQUare (Square), RAMP (Ramp), or NOISe (Noise)
as the modulating waveforms. Send the
[:SOURce[<n>]]:MOD:AM:INTernal:FREQuency or
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency command to set the frequency of
the selected modulating waveforms.
 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.
Return
Format
The query returns SIN, SQU, RAMP, or NOIS.
Example
:MOD:AM:INTernal:FUNCtion SQUare /*Sets the modulating waveforms of AM of GI to
SQUare.*/
:MOD:AM:INTernal:FUNCtion? /*The query returns SQU.*/
