Section 7: Command reference Model 2651A High Power System SourceMeter® Instrument Reference Manual
7-214 2651A-901-01 Rev. A / March 2011
Usage
sDelay = smuX.source.delay
smuX.source.delay = sDelay
sDelay
Set to your desired source delay value. For example, to specify an additional 10 ms
source delay, set the value to 0.010.
Alternatively, you can set it one of the following values:
0 or smuX.DELAY_OFF: No delay
-1 or smuX.DELAY_AUTO: Automatic delay value
X
SMU channel (for example, smua.source.delay applies to SMU Channel A).
Details
This attribute allows for additional delay (settling time) after an output step. Set sDelay to a user-defined value
(in seconds). Alternatively, set sDelay to smuX.DELAY_OFF or smuX.DELAY_AUTO.
The smuX.DELAY_AUTO setting causes a range-dependent delay to be inserted when the source is changed.
Range dependent delays are based on the output settling time values in the instrument's specifications.
Example
smua.source.delay = smua.DELAY_AUTO
Sets the delay for SMU Channel A
to automatic (a range dependent
delay is inserted when ever the
source is changed).

Usage
sFunction = smuX.source.func
smuX.source.func = sFunction
sFunction
The source function. Set to one of the following values:
0 or smuX.OUTPUT_DCAMPS: Selects current source function.
1 or smuX.OUTPUT_DCVOLTS: Selects voltage source function.
X
SMU channel (for example, smua.source.func applies to SMU Channel A).
