Voltage Bias operation mode - SMU
The Voltage Bias operation mode maintains a selected constant-voltage state at the terminal, subject
to a user-specified current 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.
Parameter Description
Bias (on page 6-36) The bias is the amount of voltage to be forced.
Force Range (on page 6-39)
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.
Power On Delay (on page 6-41)
The delay between when SMUs are powered on in a test sequence.
Pulse Mode (on page 6-41)
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).
Off Time (on page 6-43)
Available when Pulse Mode is selected. The amount of time that the pulse is
off (5 ms to 20 s).
Base Voltage (on page 6-43)
Available when Pulse Mode is selected. The voltage level that the
instrument sources when the pulse output is off. The level that you can set
depends on the present source range.
Overvoltage Protection (on page 6-
44)
A limit that restricts the maximum voltage level that the instrument can
source. It is in effect when either current or voltage is sourced.
Measure Current (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.
Current Column Name (on page 6-
44)
The name of the current measurement. This is the name that Clarius
displays in the Analyze spreadsheet column for that measurement.
Current Range (on page 6-45)
The measure range determines the full-scale measurement span that is
Available when the Measure Range is set to Limited Auto. This sets the
minimum range that the instrument uses.
Measure or Report Voltage (on page
6-45)
Determines if voltage values are recorded in the Analyze spreadsheet.
Report Value (Report Voltage or
Measure Voltage) (on page 6-46)
Determines if programmed voltage values or actual measured voltage
values are recorded in the Analyze spreadsheet.
Voltage Column Name (on page 6-
45)
The name of the voltage measurement. This is the name that Clarius
displays in the Analyze spreadsheet column for that measurement.
Report Status (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.
