Remote ohms programming
The following paragraphs summarize basic commands necessary for remote
ohms programming and also give a programming example for a typical ohms
measurement situation.
Remote ohms command
Use the following command to obtain a resistance reading:
reading = smuX.measure.r()
See Table 4-7
functions, and also
Ohms programming example
The command sequence for a typical ohms measurement is shown below. These
commands set up the SourceMeter as follows:
•
•
•
•
smua.reset()
smua.source.func = smua.OUTPUT_DCAMPS
smua.source.rangei = 10e-3
smua.source.leveli = 10e-3
smua.source.limitv = 10
smua.sense = smua.SENSE_REMOTE
smua.measure.autorangev = smua.AUTORANGE_ON --Set voltage range to auto.
smua.source.output = smua.OUTPUT_ON
print(smua.measure.r())
smua.source.output = smua.OUTPUT_OFF
