7-14 Buffer (Data Store)
Dynamically allocated buffer example
The listing below shows a programming example for storing data using an
allocated buffer called mybuffer for Channel A. The SourceMeter stores 100
current readings in mybuffer and then recalls all the readings.
smua.reset()
smua.measure.autorangei = smua.AUTORANGE_ON
format.data = format.ASCII
mybuffer = smua.makebuffer(100)
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.overlappedi(mybuffer)
waitcomplete()
smua.source.output =smua.OUTPUT_OFF
printbuffer(1, 100, mybuffer)
mybuffer = nil
