Dual buffer example
The listing below shows a programming example for storing both current and
voltage readings using buffer 1 for current and buffer 2 to store voltage readings.
The SourceMeter stores 100 current and voltage readings and then recalls all 100
sets of readings.
smua.reset()
smua.measure.autorangei = smua.AUTORANGE_ON
smua.measure.autorangev = smua.AUTORANGE_ON
format.data = format.ASCII
smua.nvbuffer1.clear()
smua.nvbuffer2.clear()
smua.measure.count = 100
smua.measure.interval = 0.1
smua.source.func = smua.OUTPUT_DCVOLTS
smua.source.levelv = 1
smua.source.output =smua.OUTPUT_ON
smua.measure.overlappediv
(smua.nvbuffer1,smua.nvbuffer2)
waitcomplete()
smua.source.output =smua.OUTPUT_OFF
printbuffer(1, 100, smua.nvbuffer1)
printbuffer(1, 100, smua.nvbuffer2)
