SCPI Programming Reference
If a trigger occurs during a measurement, that measurement is considered to be a pretrigger sample.
l
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
If any of the calculation functions are on

The instrument sets the pretrigger sample count to "0" after a Factory Reset ( *RST command) or a

Preset (SYSTem:PRESet command).

Parameter
{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
trigger 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

time is inserted between the first and second samples, the second and third, and so on:
