Current List Sweep operation mode - SMU
The Current List Sweep operation mode allows you to customize the current values for each step of
the sweep. List Sweeps allow you to make measurements only at selected forced voltages and
currents. For example, they allow you to skip unimportant measurement points or to synthesize a
custom sweep that is based on a special mathematical equation. You can also use list sweeps to
make pulsed measurements to avoid overheating of sensitive devices. The following figure illustrates
a possible list sweep.
The current sweep generates parametric curve data that is recorded in the Analyze pane.
The parameters that are available for this mode are briefly described in the following table. Select the
links to access additional information. The parameters are listed in the order in which they appear in
the All Parameters pane.

Description
(on page 6-45) The measure range determines the full-scale measurement span that is
applied to the signal.
(on page 6-46) When this option is selected, Clarius records measurement status
information when the test executes. A column of the Analyze spreadsheet
displays this information. Hover over a cell to review the information.

Select Enter Values to open a dialog box in which you can enter the current
level for each step of the sweep in the rows. You can enter any valid
instrument current.
The number of sweep points that were defined in the List Values list. This
number is automatically generated.
When you select Dual Sweep, the instrument sweeps from start to stop,
then from stop to start. When you clear Dual Sweep, the instrument sweeps
from start to stop only.

Pulse Mode allows you to apply voltage or current to a device for brief
periods at widely spaced intervals. This avoids device overheating in some
tests. Pulse Mode is only available if the source range and measure ranges
are set to a fixed range or the Best Fixed range.
