Details
This attribute contains the unit of measure that is stored with readings in the reading buffer.
Example
reset()
testData = buffer.make(50)
testData.fillmode = buffer.FILL_CONTINUOUS
smu.measure.func = smu.FUNC_DC_CURRENT
trigger.model.load("SimpleLoop", 3, 0,
testData)
trigger.model.initiate()
waitcomplete()
printbuffer(1, testData.n, testData.units)
smu.measure.func = smu.FUNC_DC_VOLTAGE
trigger.model.initiate()
waitcomplete()
printbuffer(1, testData.n, testData.units)

The name of the reading buffer, which may be a default buffer (defbuffer1 or
defbuffer2) or a user-defined buffer
The reading number N; can be any value from 1 to the number of readings in the
buffer; use the bufferVar.n command to determine the number of readings in the
buffer
Where saved
Not applicable
Create a reading buffer named testData,
configure the instrument to make three
measurements, and store the readings in
the buffer.
Set the buffer to fill continuously.
Set the measure function to current.
Make three readings.
Print the units for the readings.
Output:
Amp DC, Amp DC, Amp DC
Set the measure function to voltage.
Make three readings.
Output:
Volt DC, Volt DC, Volt DC
