makes certain that a measurement is not started until the sensor
has settled. To this end, the delay value is automatically determined. This is especially
important when thermal sensors are used. The automatically determined delay is
ignored if a longer period is set with
TRIG<[1]..4>]:DEL
.
Parameters:

TRIGger<[1]..4>:DTIMe

TRIGger:ALL:DTIMe
<dtime>
If the trigger level has been underrun with internal triggering, it is sometimes useful to
wait some time (drop-out time) before retriggering. The measurement of unwanted sig-
nal components can thus be suppressed. This setting parameter is used with pulsed
GSM signals, for example, if only specific timeslots are to be measured.
The figure below shows the importance of the drop-out time. If the timeslots BF and
DH are not to be measured, the drop-out time is set to a higher value than the period
EB (GD). In this case, the trigger events B and D are ignored.

A similar response is achieved with the
SENSe:BURSt:DTOLerance
command in the
Burst mode. However, the Burst mode makes certain that a burst measurement is not
discontinued too early, whereas
TRIGger:DTIMe
suppresses a new measurement
that is performed too early.
