[SENSe:]TEMPerature:NPLC? [{MIN|MAX|DEF}]
Sets the integration time in number of power line cycles (PLC) for temperature 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.

0.001, 0.002, 0.006, 0.02, 0.06, .2, 1, 10, 100. Default: 10

l
Selecting an integration time in power line cycles overrides an aperture set with the
command.
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.
shows the rela-
tionship between integration time and resolution.

This parameter is set to its default value after a Factory Reset (
) or Instrument Preset
(
).
