Description This command is used to set the integration period (speed) for measure-
ments. 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 would be 1/60 (for 60Hz line power) which
is 16.67 msec.
Note that this is a global command. Thus, if you set the speed for chan-
nel 1 measurements to 10 PLC, then channel 2 will also set to 10 PLC.
