Configuring compliance limits remotely
You can configure voltage and current limits using the smuX.trigger.source.limitY attribute,
which sets the sweep source limits. For example, to set the SMU A sweep limit to 10 V, send the
command:
smua.trigger.source.limitv = 10
Configuring end sweep actions remotely
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
smuX.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
Configuring measurements during a sweep
You can make measurements during a sweep using the smuX.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 stores 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 keys to
choose 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 be done only 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 3-1) for details about recalling data from the buffer.
