Usage
nplc = smuX.measure.nplc
smuX.measure.nplc = nplc
nplc
The integration aperture. Set from 0.001 to 25 (in seconds).
X
SMU channel (for example, smua.measure.nplc applies to SMU Channel A).
Details
When making measurements, the SMU uses one of two types of analog to digital converters. This attribute
controls the integration aperture for the integrating ADC. This attribute is not used when the fast ADC is selected.
The integration aperture is based on the number of power line cycles (NPLC), where 1 PLC for 60 Hz is 16.67
ms (1/60) and 1 PLC for 50 Hz is 20 ms (1/50).
Example
smua.measure.nplc = 0.5
Sets the integration time for SMU Channel A to 0.5/60
seconds.
