Voltage Linear Sweep operation mode - SMU
When you select the Voltage Linear Sweep operation mode, the test increments through a series of
constant voltage steps. You define the start and stop voltages and the voltage size between each
step. An example is shown in the next figure.
The voltage 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
The voltage source level at which the sweep starts.
The voltage source level at which the sweep stops.
The voltage size of each step of the sweep. The source level changes in
equal steps of this size from the start level to the stop level. A measurement
is made at each source step (including the start and stop levels).
The number of data points that will be measured. This value is calculated by
Clarius using the information entered for the Start, Stop, and Step
parameters.
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.
(on The SMU range that is used when forcing the voltage.
A limit that stops the 4200A-SCS from sourcing a current that is more than
that limit.
(on page 6-41) The delay between when SMUs are powered on in a test sequence.
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.
Available when Pulse Mode is selected. The amount of time that the pulse is
on (5 ms to 20 s).
