The SMU will only store the most recent configured source action. The last call to
smu X .trigger.source.linear Y ()
,
smu X .trigger.source.list Y ()
, or
smu X .trigger.source.log Y ()
is used for the source action.
Source functions cannot be changed within a sweep.
After configuring the sweep source values, enable the source action by setting
smu X .trigger.source.action
.
Example
smua.trigger.source.logv(1, 10, 11, 0)
Sweeps SMU channel A from 1 V
to 10 V in 10 steps with an
asymptote of 0 V.

smuX.trigger.source.set()
This function sets the source event detector to the detected state.
Type TSP-Link accessible Affected by Where saved Default value
Function Yes
Usage
smu X .trigger.source.set()
X
Source-measure unit (SMU) channel (for example,
smua.trigger.source.set()
applies to SMU channel A)
Details
This function sets the source event detector to the detected state.
The SMU will automatically clear all event detectors when the
smu X .trigger.initiate()
function is
executed. This function should be called after the sweep is initiated. Make sure that if the event detectors are
configured to automatically clear (because the
smu X .trigger.autoclear
attribute is set to
smu X .ENABLE
)
that this command is issued after the SMU has entered the trigger layer.
