Smu.measure.userdelay[N] - Keithley 2461 Reference Manual

Section 8: TSP command reference

smu.measure.userdelay[N]

This attribute sets a user-defined delay that you can use in the trigger model.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
delayTime = smu.measure.userdelay[N]
smu.measure.userdelay[N] = delayTime
delayTime
N
Details
To use this command in a trigger model, assign the delay to the dynamic delay block.
The delay is specific to the selected function.
Example
smu.measure.userdelay[1] = 5
trigger.model.setblock(1, trigger.BLOCK_SOURCE_OUTPUT, smu.ON)
trigger.model.setblock(2, trigger.BLOCK_DELAY_DYNAMIC,
trigger.USER_DELAY_M1)
trigger.model.setblock(3, trigger.BLOCK_MEASURE)
trigger.model.setblock(4, trigger.BLOCK_SOURCE_OUTPUT, smu.OFF)
trigger.model.setblock(5, trigger.BLOCK_BRANCH_COUNTER, 10, 1)
trigger.model.initiate()
Set user delay for measure 1 to 5 s.
Set trigger block 1 to turn the source output on.
Set trigger block 2 to a dynamic delay that calls measure user delay 1.
Set trigger block 3 to make a measurement.
Set trigger block 4 to turn the source output off.
Set trigger block 5 to branch to block 1 ten times.
Start the trigger model.
