The asymptote parameter can be used to customize the inflection and offset of the source value
curve. This allows log sweeps to cross zero. Setting this parameter to zero provides a conventional
logarithmic sweep. The asymptote value is the value that the curve has at either positive or negative
infinity, depending on the direction of the sweep.
The asymptote value must not be equal to or between the starting and ending values. It must be
outside the range defined by the starting and ending values.
The SMU stores only the most recent configured source action. The last call to
smuX.trigger.source.linearY(), smuX.trigger.source.listY(), or
smuX.trigger.source.logY() 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
smuX.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

Function Yes
Usage
smuX.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 automatically clears all event detectors when the smuX.trigger.initiate() function is
executed. This function should be called after the sweep is initiated. If the event detectors are
configured to clear automatically because the smuX.trigger.autoclear attribute is set to
smuX.ENABLE, make sure that smuX.trigger.source.set() is issued after the SMU has
entered the trigger layer.
