REMOTE INTERFACE
225
Sets the modulation source to external.
Query Syntax SOURce[1]:AM:SOURce?
Return Parameter INT Internal
EXT External
Example SOUR1:AM:SOUR?
INT
The modulation source is set to internal.
SOURce[1]:AM:INTernal:FUNCtion
Source Specific
Command
Description Sets the shape of the modulating waveform from
sine, square, triangle, upramp and dnramp. The
default shape is sine.
Note Square and triangle waveforms have a 50% duty
cycle. Upramp and dnramp have a symmetry of
100% and 0%, respectively.
Syntax SOURce[1]:AM:INTernal:FUNCtion
{SINusoid|SQUare|TRIangle|UPRamp|DNRamp}
Example SOUR1:AM:INT:FUNC SIN
