SCPI Programming Reference
After setting the sample count and pretrigger sample count, you must place the DMM in the "wait-
l
for-trigger" state using
for-trigger" state.
The pretrigger sample count must be less than the sample count set with the
l
mand, and there must be at least one post-trigger sample:
Pretrigger Sample Count ≤ Sample Count - 1

The instrument sets the pretrigger sample count to "0" after a Factory Reset ( *RST command) or a Pre-
l
set (SYSTem:PRESet command).

{IMMediate|TIMer}. Default: IMMediate.
Set sample source to timer. The INIT command sets the meter to the "wait-for-trigger" state. When a trig-
ger is received from the selected trigger source, the instrument starts taking periodic samples after the trig-
ger delay.

Operation
In all cases, the first sample is taken one trigger delay time after the trigger (the delay being set with the
TRIGger:DELay command). Beyond that, the timing mechanism depends on whether you select IMMe-
diate (default) or TIMer as the source:
IMMediate - The first sample starts one trigger delay time after the trigger, and then the trigger delay
