<sm.source.delay
This attribute contains the source delay.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW)
Yes
SMU reset

Not saved
0 (smuX.DELAY_OFF)
Usage
sDelay = smuX.source.delay
smuX.source.delay = sDelay
sDelay
Set to the 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 smu
X
.DELAY_AUTO: Automatic delay value
X
Source-measure unit (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 as defined in the
Series 2600B specifications.
Example
smua.source.delay = smua.DELAY_AUTO
Sets the delay for SMU channel A
to automatic (a range-dependent
delay is inserted whenever the
source is changed).
