The modulation source is set to internal.
SOURce[1]:FM:INTernal:FUNCtion
Set
Query
Description Sets the shape of the modulating waveform from
sine, square or ramp. The default shape is sine.
Note
Square waveforms have a 50% duty cycle. Ramp
waveforms have a symmetry of 100%.
Syntax SOURce[1]:FM:INTernal:FUNCtion
{SINusoid|SQUare|RAMP }
Example SOUR1:FM:INT:FUNC SIN
Sets the FM modulating wave shape to sine.
Query Syntax SOURce[1]:FM:INTernal:FUNCtion?
Return Parameter SIN Sine
