TRIGger:DELay {<
seconds
>|MIN|MAX|DEF}
TRIGger:DELay? [{MIN|MAX|DEF}]
Sets the delay between the trigger signal and the first measurement. This may be useful in applications
where you want to allow the input to settle before taking a measurement or for pacing a burst of meas-
urements.
Selecting a specific trigger delay disables the automatic trigger delay (
).
For AC measurements (voltage or current), there is a relationship between the bandwidth
setting (
or
) and the default trigger delay setting. This delay
ensures that there is sufficient settling time for the AC measurement. See
for further information.
Parameter
Typical Return
0 to ~3600 seconds (~1 µs steps). Default: 1 s.
Step size for DC measurements is approximately 1 µs.
Step size depends on AC bandwidth for AC measurements.
+2.0000
Return five DC voltage measurements. There is a 2 second delay before each measurement.

l
Due to internal quantization, the actual delay that you set may be slightly different than your specified
value. The increment is approximately 1 µs.
l
By default,
is ON. The instrument automatically determines the delay based on
function, range and integration time (see
). However, you may need to set a
delay longer than the automatic delay for long cables, high capacitance or high impedance signals.
l
If you specify a trigger delay with this command, that delay is used for
all
functions (
except
and
) and ranges. The CONTinuity and DIODe tests ignore the trigger delay setting.
l
If you have configured the instrument for more than one measurement per trigger (
>1), the delay is inserted after the trigger and between consecutive measurements.
l
The instrument selects automatic trigger delay after a Factory Reset (
) or an Instrument Preset
(
).
