Speed Commands
: NPLCycles
Command System:
:RESistance:NPLCycles Set NPLC for Ω
Command Parameter:
= 0.1, 1, 10 Set power line cycles per integration
DEFault 1
MINimum 10
MAXimum 0.1
Query:
:NPLCycles? Query programmed NPLC value
Description:
The integration period (measurement speed) for the basic measurement functions (except
Frequency and Period) is set using the :NPLCycles command. NPLC (Number of Power Line
Cycles) expresses the integration period by basing it on the power line frequency. For example, for a
PLC of 1, the integration period in seconds would be 1/60 (for 60Hz line power) which is 16.67 ms.
