smua.pulser.measure.delay
This attribute sets the measurement delay when the pulser is enabled.

Usage
delay = smua.pulser.measure.delay
smua.pulser.measure.delay = delay
The measurement delay value in seconds; set from 0 to 0.065
Details
Use this attribute with the trigger model when performing a pulse sweep.
Set the delay parameter to a nonzero value to specify when a measurement starts during a pulse.
The measurement starts after the delay interval expires. This allows the 2601B-PULSE to locate
measurements within a pulse with less jitter than those generated using the measure trigger stimulus
in the trigger model.
The sum of the measure delay and the total measure time must be less than the pulse width
configured with the smua.trigger.source.pulsewidth setting. The total measure time depends
on the measure count, the filter count, and the measure interval.
You cannot use this attribute and a measurement stimulus in the trigger model at the same time.
Using both the end-pulse stimulus and this attribute in a script may cause the pulse output to
end before the specified duration of the pulse is completed, causing invalid measurements.
When this attribute is set to zero, measurements are only triggered by a measurement stimulus.
The settings for this attribute are ignored if the pulser is disabled.
Example
smua.pulser.measure.delay = 35e-6
smua.pulser.measure.aperture = 10e-6
Specify a 35 µs pulse measure delay and a 10 µs measurement aperture.
