Example SOUR1:PWM:SOUR?
INT
The PWM source is set to internal.
SOURce[1]:PWM: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 to
100% and 0%, respectively.
Carrier must be a pulse or PWM waveform.
Syntax SOURce[1]:PWM:INTernal:FUNction
{SINusoid|SQUare|TRIangle|UPRamp|DNRamp}
Example SOUR1:PWM:INT:FUN SIN

SOURce[1]:PWM:INTernal:FREQuency
Source Specific
Command
Description Sets the modulating waveform frequency for
internal sources. The default frequency is set to
10Hz.
Syntax SOURce[1]:PWM:INTernal:FREQuency
