To set the number of PLCs for resistance measurements, send the command:
:SENSe:RESistance:NPLCycles <n>
To set NPLCs for voltage measurements, send the command:
:SENSe:VOLTage:NPLCycles <n>
Where <n> is a value from 0.01 to 10, with 0.01 resulting in the fastest reading rates and 10 resulting
i
n the lowest reading noise.
For example, to set NPLC for resistance measurements to 0.5, send the command
RES:NPLC 0.5
Using TSP commands:
To set NPLC, send the command smu.measure.nplc. For example, to set the NPLC value to 0.

f
or voltage measurements, send the commands:
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.nplc = 0.5
To assign a different measure function, replace smu.FUNC_DC_VOLTAGE with one of the following:
• For current measurements: smu.FUNC_DC_CURRENT
• For resistance measurements: smu.FUNC_RESISTANCE
