Reference Manual
8-34 2461-901-01 A/November 2015
The values returned by this command depend on the source readback state:
• If readback is off, the value is the programmed value
• If readback is on, the value is the actual measured source value
Example
reset()
testData = buffer.make(50)
smu.source.func = smu.FUNC_DC_CURRENT
smu.source.level = 1e-6
smu.source.output = smu.ON
trigger.model.load("SimpleLoop", 3, 0, testData)
trigger.model.initiate()
waitcomplete()
printbuffer(1, 3, testData.sourcevalues)
Create a reading buffer named
testData, configure the instrument to
make three measurements, and store
the readings in the buffer.
Set the source value to 1e-6 A.
Print the source values being output
when readings in the reading buffer
were acquired.
Example output:
9.9999874692e-07,
1.0000017028e-06,
1.0000054544e-06
