Current Linear Sweep operation mode - SMU
When you select the Current Linear Sweep operation mode, the test increments through a series of
constant current steps. You define the start and stop currents and the current size between each
step.
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
The current source level at which the sweep starts.
The current source level at which the sweep stops.
The current size of each step of the sweep. The current 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.
The SMU range that is used when forcing the current.
A limit that stops the 4200A-SCS from sourcing a voltage that is more than
that limit.
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).
Available when Pulse Mode is selected. The amount of time that the pulse is
off (5 ms to 20 s).
Available when Pulse Mode is selected. The current level that the
instrument sources when the pulse output is off. The level that you can set
depends on the present source range.
A limit that restricts the maximum voltage level that the instrument can
source. It is in effect when either current or voltage is sourced.
When this box is selected, the instrument measures current. Current is
recorded in the Analyze sheet and shown in the graph.
The Report Value setting determines which current values are recorded in
the Analyze spreadsheet.
The name of the current measurement. This is the name that Clarius
displays in the Analyze spreadsheet column for that measurement.
When this box is selected, the instrument measures voltage. Voltage is
recorded in the Analyze sheet and shown in the graph.
The name of the voltage measurement. This is the name that Clarius
displays in the Analyze spreadsheet column for that measurement.
