Usage
:TRIGger:BLOCk:DELay:CONStant <blockNumber>, <time>
<blockNumber>
The sequence of the block in the trigger model
<time>
The amount of time to delay in seconds (50
µ
s to 10000 s, or zero)
Details
When the trigger model reaches a delay building block, it stops operation for the amount of time set by the delay.
This delay is a fixed amount of time. If other delays have been set, this delay is in addition to the other delays.

INIT
Create configuration lists named ampLevel and
biasLevel.
Set the source function to 5 volts and the
measurement function to current.
Store the settings in the ampLevel
configuration list.
Set the voltage level to 0.
Store the setting in the biasLevel
configuration list.
Set block 1 to turn the source output on.
Set block 2 to recall the ampLevel settings.
Set block 3 to provide a constant delay of
0.1 seconds.
Set block 4 to make a measurement.
Set block 5 to recall the biasLevel settings.
Set block 6 to provide a constant delay of 0.2.
Set block 7 to repeat block 2 nineteen times.
