Current Bias operation mode - SMU
Current Bias operation mode maintains a selected constant-current state at the terminal, subject to
the maximum voltage compliance of the connected SMU.
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- The name of the voltage measurement. This is the name that Clarius
displays in the Analyze spreadsheet column for that measurement.
(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.
Description
The bias is the amount of current to be forced.
(on page 6-39) 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.
(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).
Available when Pulse Mode is selected. The amount of time that the pulse is
off (5 ms to 20 s).
(on page 6-43) 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.
(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.
(on page 6- The name of the voltage measurement. This is the name that Clarius
displays in the Analyze spreadsheet column for that measurement.
(on page 6-45) The measure range determines the full-scale measurement span that is
applied to the signal.
