Restore defaults with this command:
*RST
Configure the waveform.
Examples – The following commands configure a 10kHz square wave with
an amplitude of 1mA, 0mA offset, 50% duty cycle, 180° phase marker, and
10 second duration:
SOUR:WAVE:FUNC SQU
SOUR:WAVE:FREQ 1e4
SOUR:WAVE:AMPL 1e-3
SOUR:WAVE:OFFS 0
SOUR:WAVE:DCYC 50
SOUR:WAVE:PMAR:STAT ON
SOUR:WAVE:PMAR 180
SOUR:WAVE:PMAR:OLIN 1
SOUR:WAVE:DUR:TIME 10
SOUR:WAVE:RANG BEST
Arm and trigger the waveform, turn on output:
SOUR:WAVE:ARM
SOUR:WAVE:INIT
To stop generating the waveform and turn the source output off before the
duration elapses, send this command:
SOUR:WAVE:ABOR
