Model 2601B-PULSE System SourceMeter Instrument Reference Manual Section 4: Sourcing and measuring
2601B-PULSE-901-01A April 2020 4-25
DUT connection settings
This section describes the sense mode and output-off state settings.
Sense mode selection
When the pulser is disabled, the voltage sense mode can be set to use 2-wire local sensing
connections (on page 4-10) or 4-wire remote sensing connections (on page 4-10). The default sense
setting is 2-wire local.
When the pulser is enabled, the sense mode is fixed at 4-wire remote sensing and the sense mode
settings are ignored.
Front panel sense mode selection
To check or change the voltage sense mode from the front panel:
1. Press the CONFIG key.
2. Press the SRC or MEAS key. You can access and set the 2601B-PULSE sense mode from either
the V-SOURCE or the V-MEAS menu items.
3. If you pressed the SRC key: select V-SOURCE > SENSE-MODE, and then press the ENTER key
or the navigation wheel .
If you pressed the MEAS key: select V-MEAS > SENSE-MODE, and then press the ENTER key
or the navigation wheel .
4. Select 2-WIRE or 4-WIRE as needed, and then press the ENTER key or the navigation wheel .
Selecting the sense mode from the remote interface
To select the voltage sense mode from the remote interface:
To configure the 2601B-PULSE SMU for 4-wire remote sensing, send the command:
smua.sense = smua.SENSE_REMOTE
The following table summarizes the commands to select the sense mode. See the TSP command
reference (on page 11-1) for details on using these commands.
Commands to select sense mode
smua.source.output = smua.OUTPUT_OFF
Turns off the source-measure unit (SMU) output.
smua.sense = smua.SENSE_LOCAL
Select local (2-wire) sense.
smua.sense = smua.SENSE_REMOTE
Select remote (4-wire) sense.
