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 (TRIGger:DELay:AUTO OFF).
For AC measurements (voltage or current), there is a relationship between the bandwidth
setting ([SENSe:]VOLTage:AC:BANDwidth or
[SENSe:]CURRent:AC:BANDwidth) and the default trigger delay setting. This delay
ensures that there is sufficient settling time for the AC measurement. See Automatic
Trigger Delays 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.
+2.00000806E+00
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, TRIGger:DELay:AUTO is ON. The instrument automatically determines the delay based on
function, range and integration time (see Automatic Trigger Delays). 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 CONTinu-
ity and DIODe) 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 (SAMPle:COUNt
>1), the delay is inserted after the trigger and between consecutive measurements.
l The instrument selects automatic trigger delay after a Factory Reset (*RST) or an Instrument Preset
(SYSTem:PRESet).
