Section 4: Sourcing and measuring Model 2601B-PULSE System SourceMeter Instrument Reference Manual
4-72 2601B-PULSE-901-01A April 2020
Configuring end sweep actions remotely
When the pulser is disabled, use the end sweep action to configure the source action at the end of
the sweep. The source-measure unit (SMU) can be programmed to return to the idle source level or
hold the last value of the sweep. Configure the end sweep action by setting the
smua.trigger.endsweep.action attribute. For example, execute the following command to
configure SMU A to return the source to the idle source level at the end of a sweep:
smua.trigger.endsweep.action = smua.SOURCE_IDLE
When the pulser is enabled, the instrument ignores the actual setting of
smua.trigger.endsweep.action and behaves as if it is set to smua.SOURCE_IDLE.
Configuring measurements during a sweep
You can make measurements during a sweep using the smua.trigger.measure.Y() function.
When sweeps are run, measurements are stored in the specified reading buffer for later recall. You
can specify which reading buffer will store the readings. For example, to store the voltage readings
made during the sweep, send the commands:
smua.trigger.measure.v(vbuffername)
smua.trigger.measure.action = smua.ENABLE
To recall sweep data using the front panel:
1. Press the RECALL key.
2. Select DATA or STATISTICS.
3. If you selected DATA: Select the buffer, and then use the navigation wheel or cursor
keyschoose reading numbers to display .
4. If you selected STATISTICS: Select the buffer, and then use the navigation wheel or cursor
keys to choose MEAN, STD DEV, SAMPLE SIZE, MINIMUM, MAXIMUM, or PK-PK.
Recalling readings from the reading buffer using the front panel can only be done if one of the
dedicated reading buffers is used to store the sweep data.
To recall sweep data using remote commands:
• Use the printbuffer() function to request buffer readings.
See Reading buffers (on page 5-1) for details about recalling data from the buffer.
