Model 4200A-SCS Parameter Analyzer Reference Manual
Current Step operation mode - SMU
The Current Step operation mode increments through evenly-spaced, constant current steps over a
range that you specify. The time interval for each step is determined automatically by the time
required to complete a sweep.
For each step, parametric curve data is generated 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 that is forced for the first step value.
The current that is forced for the last step value.
The current 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.
(on The SMU range that is used when forcing the current.
(on page 3-3) A limit that stops the 4200A-SCS from sourcing a voltage that is more than
that limit.
(on page 6-41) The delay between when SMUs are powered on in a test sequence.
(on page 6- A limit that restricts the maximum voltage level that the instrument can
source. It is in effect when either current or voltage is sourced.
(on page 6-44) 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
(on page 6-46) the Analyze spreadsheet.
(on page 6- The name of the current measurement. This is the name that Clarius
displays in the Analyze spreadsheet column for that measurement.
(on page 6- When this box is selected, the instrument measures voltage. Voltage is
recorded in the Analyze sheet and shown in the graph.
