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.
