Example:
*RST
TRIG:SOUR INT
TRIG:DEL 50 us
(starts measurement 50 µs after the trigger event)
TRIG:HOLD 800 us
(starts next trigger event 800 µs after the trigger event at the earliest)

Another way to modify the trigger system timing is to set a holdoff time (
TRIG:HOLD
). After a trigger
event, all following trigger events are ignored if they occur within the holdoff time. This is to prevent
signal components that have not yet decayed from causin triggering by mistake after the measurement
has been completed. This makes sense especially with internal triggering (BurstAv mode).

It is also possible to exclude time domains from the integration of the measured value at the beginning
and the end of the measurement (
SENS:TIM:EXCL:STARt
and
SENS:TIM:EXCL:STOP
):
Example:
*RST
SENS:FUNC "POW:BURS:AVG"
SENS:TIM:EXCL:STAR 10 US
(ignores 10 µs at the beginning of the measurement)
SENS:TIM:EXCL:STOP 10 US
(ignores 10 µs at the end of the measurement)
