smuX.measure.delay
This attribute controls the measurement delay.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Instrument reset
SMU reset
Not saved smuX.DELAY_OFF
Usage
mDelay = smuX.measure.delay
smuX.measure.delay = mDelay
mDelay
Set to your desired measurement delay value (for example, to specify an additional
10 ms measurement delay, set the value to 0.010)
You can also set it one of the following values:
0 or smuX.DELAY_OFF: No delay
-1 or smuX.DELAY_AUTO: Automatic delay value
X
Source-measure unit (SMU) channel (for example, smua.measure.delay applies
to SMU channel A).
Details
This attribute allows for additional delay (settling time) before taking a measurement. You can set mDelay to
smuX.DELAY_OFF, smuX.DELAY_AUTO, or to a user-defined value (in seconds). A user-defined value will set
the delay used, regardless of range.
The smuX.DELAY_AUTO setting also causes a current range-dependent delay to be inserted when a current
measurement is requested. This happens when a current measurement command is executed, when the
measure action is being performed in a sweep, or after changing ranges during an autoranged measurement.
If smuX.measure.count is greater than 1, the measurement delay is only inserted before the first
measurement.
Example
smua.measure.delay = 0.010
Sets a 10 ms measurement delay for SMU channel A.
