Trigger Delay
In some applications, you want to allow the input to settle before taking a reading
or for pacing a burst of readings. You can add a trigger delay, which adds a delay
between the trigger signal and the first sample taken by the internal DMM (not
used in Scanning Mode). The programmed trigger delay overrides the default
trigger delay that the instrument automatically adds to the measurement.
Trigger delay
– The default trigger delay is Automatic (see “Automatic Trigger Delays” on
page 130); the instrument determines the delay based on function, range, and
integration time.
– If you specify a trigger delay other than Automatic, that same delay is used for
all functions and ranges.
– If you have configured the instrument to take more than one reading per
trigger (sample count > 1), the specified trigger delay is inserted between the
trigger and the first reading in the sample burst.
–The CONFigure and MEASure? commands set the trigger delay to Automatic.
– The instrument selects an automatic trigger delay after a Factory Reset (*RST
command). An Instrument Preset (SYSTem:PRESet command) or Card Reset
(SYSTem:CPON command) does not change the setting.
