[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 sig-
nal for a measurement. A longer integration time gives better measurement resolution but slower meas-
urement speed.
Parameter
Typical Return
0.02, 0.2, 1, 10, 100. Default: 10 (34460A/61A)
0.02, 0.06, 0.2, 1, 10, 100. Default: 10 (34465A/70A without
DIG option)
0.001, 0.002, 0.006, 0.02, 0.06, .2, 1, 10, 100. Default: 10

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.
