Restore defaults with this command:
*RST
Configure the desired waveform using one of the procedures previously
described for a sine, square, ramp, or arbitrary waveform.
Configure the low jitter external trigger mode.
Examples – The following commands configure the selected waveform to
be output following each pulse received on trigger link line 1. If a
subsequent trigger pulse is received while the waveform is being output,
the Model 6221 will immediately terminate the current wave and restart the
waveform. In between waveforms, the unit will output zero current.
SOUR:WAVE:EXTR:ENAB ON
SOUR:WAVE:EXTR:ILIN 1
SOUR:WAVE:EXTR:IGN OFF
SOUR:WAVE:EXTR:IVAL 0.00 ' Output zero current between waves.
Arm and trigger the waveform to enable the output. The Model 6221 will
wait for an external trigger pulse on the specified trigger link line and start
the waveform within 1μs:
SOUR:WAVE:ARM
SOUR:WAVE:INIT
To stop the Model 6221 from responding to triggers and immediately stop
any waveform being generated by turning the source output off, send this
command:
SOUR:WAVE:ABOR

' Turn on external trigger mode.
' Use TLINK Line 1 as input trigger.
' Restart wave on retrigger attempts.
' Arm waveform.
' Enable output, wait on external triggers.
' Stop generating waveforms.
