GW Instek MFG-2000 Series User Manual

REMOTE INTERFACE
325
The PWM source is set to internal.
SOURce[1|2|3]: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.

SOURce[1|2|3]:PWM:INTernal:FREQuency
Source Specific
Command
Description
Sets the modulating waveform frequency for
internal sources. The default frequency is set to
10Hz.
Syntax
