[SENSe:]VOLTage[:DC]:NPLC {<PLC>|MIN|MAX|DEF}
[SENSe:]VOLTage[:DC]:NPLC? [{MIN|MAX|DEF}]
Sets the integration time in number of power line cycles (PLC) for DC voltage and ratio measurements. Integration
time is the period that the instrument's analog-to-digital (A/D) converter samples the input signal for a measurement.
A longer integration time gives better measurement resolution but slower measurement speed.
Parameter Typical Return
{0.02|0.2|1|10|100}, default 10
See Range, Resolution and NPLC for more information.
+1.00000000E+01
Configure DC voltage measurements using a 10 PLC integration time. Then make and read one measurement:
CONF:VOLT:DC
VOLT:DC:NPLC 10
READ?
Typical Response: +6.27530000E-01
l Only integration times of 1, 10, or 100 PLC provide normal mode (line frequency noise) rejection.
l Setting the integration time also sets the measurement resolution.Resolution Table shows the relationship
between integration time and resolution. See [SENSe:]VOLTage[:DC]:RESolution.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset (SYSTem:PRESet).
[SENSe:]VOLTage[:DC]:RESolution{<resolution>|MIN|MAX|DEF}
[SENSe:]VOLTage[:DC]:RESolution? [{MIN|MAX|DEF}]
Selects the measurement resolution for DC voltage and ratio measurements. Specify the resolution in the same units
as the selected measurement function, not in number of digits.
Parameter Typical Return
<resolution>: See Resolution Table or Range, Resolution and NPLC. The default is
equivalent to 10 PLC. Specify <resolution> in the measurement's units (V, A, Hz, Ω, and
so on).
+3.00000000E-05
Configure DC voltage measurements with a 3 µV resolution. Then make and read one measurement:
CONF:VOLT:DC 1
VOLT:DC:RES 3E-6
READ?
l You can specify MIN (best resolution) or MAX (worst resolution) instead of <resolution>.
l To achieve normal mode (line frequency noise) rejection, use a resolution that corresponds to an integration time
that is an integral number of power line cycles.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset (SYSTem:PRESet).
