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.
