FRESistance:NPLC

[SENSe:]FRESistance:NPLCycles <number> sets the integration time in number of power line cycles (NPLCs). The NPLC is set to a value from the range of values that can accommodate the <number> you specify. For example, specifying 9 sets the NPLC to 10; specifying 11 sets the NPLC to 100.

Comments MINimum selects 0.02 PLCs. MAXimum selects 100 PLCs. Setting the integration time in power line cycles (PLCs) also sets the aperture time and the resolution. For example, 10 PLCs sets an aperture time of 167ms (60Hz line frequency) or 200ms (50Hz). The corresponding resolution depends on the function and range you select.

The FRES:NPLC command overrides the results of previously executed

FRESistance:APERture and FRESistance:RESolution commands (the last command executed has priority).

The greater the number of PLCs, the greater the normal mode rejection (and the lower the reading rate).

Only the 1 PLC, 10 PLC and 100 PLC settings provide normal mode rejection of 50Hz or 60Hz power line related noise. The 0.02 and 0.2 fractional PLC settings do not provide normal mode rejection of power line related noise.

*RST Condition: 10 PLC

Example Set the Integration Time in PLCs

FRES:NPLC 100

Integration time is 100 PLCs.

FRESistance:NPLC?

[SENSe:]FRESistance:NPLC? [MINMAX] returns one of the following numbers to the output buffer:

The present integration time in PLCs if MINimum or MAXimum is not specified.

The minimum integration time available (0.02) if MIN is specified.

The maximum integration time available (100) if MAX is specified.

Example Query the Integration Time

FRES:NPLC 100

Integration time is 100 PLCs.
