Low-current measurement programming example
The command sequence for typical low-current measurements is shown below. The sequence
assumes that a 100G
Ω
resistor is being tested. These commands set the output voltage to 100V
and then measure and display both the current through the device as well as the resistance.
smua.reset()
- Restore defaults.
smua.source.func = smua.OUTPUT_DCVOLTS
- Set source to DCV.
smua.source.rangev = 200
- Select 200V source range
smua.source.levelv = 100
- Output 100V DC.
smua.measure.rangei = 1e-9
- Select 1nA range.
smua.source.limiti = 1e-9
- Set current limit to 1nA
smua.source.output = smua.OUTPUT_ON
- Turn on output.
print(smua.measure.i())
- Display current reading.
print(smua.measure.r())
- Display resistance reading.
smua.source.output = smua.OUTPUT_OFF
- Turn off output.
