Series 2600 System SourceMeters Reference Manual Buffer (Data Store) 7-13

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() --Restore Series 2600 defaults.
smua.measure.autorangei = smua.AUTORANGE_ON --Select measure I auto range.
smua.measure.autorangev = smua.AUTORANGE_ON --Select measure V auto range.
format.data = format.ASCII --Select ASCII data format.
smua.nvbuffer1.clear() --Clear buffer 1.
smua.nvbuffer2.clear() --Clear buffer 2.
smua.measure.count = 100 --Set buffer count to 100.
smua.measure.interval = 0.1 --Set measure interval to 0.1s.
smua.source.func = smua.OUTPUT_DCVOLTS --Select source voltage function.
smua.source.levelv = 1 --Output 1V.
smua.source.output =smua.OUTPUT_ON --Turn on output.
smua.measure.overlappediv
(smua.nvbuffer1,smua.nvbuffer2)
--Store current readings in buffer 1,
voltage readings in buffer 2.
waitcomplete() --Wait for buffer to fill.
smua.source.output =smua.OUTPUT_OFF --Turn off output.
printbuffer(1, 100, smua.nvbuffer1) --Return buffer 1 readings 1-100.
printbuffer(1, 100, smua.nvbuffer2) --Return buffer 2 readings 1-100.
