[:SOURce[<n>]][:MOD]:AM:INTernal:FUNCtion {SINusoid|SQUare|TRIangle|RAMP|NRAMp|NOISe|USER}
[:SOURce[<n>]][:MOD]:AM:INTernal:FUNCtion?
Description
Sets the AM modulation waveform of the specified channel.
Queries the AM modulation waveform of the specified channel.

SINusoid
Remarks
This command is only applicable to the internal modulation source.
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
SQUare: 50% duty cycle; TRIangle: 50% symmetry; RAMP: 100% symmetry; NRAMp: 0% symmetry;
USER: the arbitrary waveform selected for the specified channel.
Return Format
The query returns SIN, SQU, TRI, RAMP, NRAM, NOIS, or USER.
Example
:SOUR1:AM:INT:FUNC SQU /*Sets the AM modulation waveform of CH1 to Square.*/
:SOUR1:AM:INT:FUNC? /*Queries the AM modulation waveform of CH1 and the query returns SQU.*/

[:SOURce[<n>]][:MOD]:AM:SOURce?
Description
Sets the AM modulation source of the specified channel to internal (INTernal) or external (EXTernal)
modulation source.

Remarks
DG900 can receive modulating waveform from the internal or external modulation source.
When the internal modulation source is selected, the modulation waveform can be SINusoid, SQUare,
TRIangle, RAMP, NRAMp, NOISe, or USER. The default is SINusoid. NOISe can be used as the
modulation waveform but cannot be used as carrier waveform.
When the external source is selected, the generator receives the external modulating signal from the
rear-panel [Sync/Ext Mod/Trig/FSK] connector. At this time, amplitude of the modulated
waveform is controlled by the ±5 V signal level of the connector. For example, if the modulation depth
is set to 100%, the output amplitude will be the maximum when the modulating signal is +5 V and the
minimum when the modulating signal is -5 V.
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
