Example:
-- Configure a sweep from 1 to 10 V in 10 steps with an asymptote of 0 V.
smua.trigger.source.logv(1, 10, 11, 0)
-- Enable the source action.
smua.trigger.source.action = smua.ENABLE

(on page 7-245).
List sweeps
Use a list sweep to configure a sweep with arbitrary steps. When enabled, a measurement is made at
each point after source and measurement settling time.
To configure a list sweep, use the
smu
X
.trigger.source.list
Y
()
function*. This function
configures the source values that the source-measure unit (SMU) will output when performing a list
sweep. After configuring the sweep, you must also enable the source action by setting the
smu
X
.trigger.source.action
attribute.
* smu
X
can be
smua
for SMU Channel A or
smub
for SMU Channel B
Example:
-- Sweep through 3 V, 1 V, 4 V, 5 V, and 2 V.
smua.trigger.source.listv({3, 1, 4, 5, 2})
-- Enable the source action.
smua.trigger.source.action = smua.ENABLE
When the sweep is started, the output level goes to the first point in the sweep. The sweep will
continue through the steps in the order that they were programmed.
The following figure shows a different example of a list sweep with six measurement points. When the
sweep starts, the current or voltage goes to the first point in the sweep. The unit cycles through the
sweep points in the programmed order.
