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.
Parameters
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? [MIN|MAX] 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.
FRES:NPLC?
Query multimeter to return integration time.
