17-60 SCPI Command Reference
Set measurement speed
:NPLCycles <n>
[:SENSe[1]]:CURRent[:DC]:NPLCycles <n> Set speed (PLC)
[:SENSe[1]]:VOLTage[:DC]:NPLCycles <n> Set speed (PLC)
[:SENSe[1]]:RESistance:NPLCycles <n> Set speed (PLC)
Parameters <n> = 0.01 to 10 Power-line cycles per integration
DEFault 10
MINimum 0.01
MAXimum 10
Query :NPLCycles? Query programmed PLC value
:NPLCycles? DEFault Query *RST default PLC
:NPLCycles? MINimum Query minimum PLC
:NPLCycles? MAXimum Query maximum PLC
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 voltage
measurements to 10 PLC, then current and resistance will also set to 10
PLC.
Configure and control filters
NOTE Detailed information on the repeat, median and moving filters are provided in Sec-
tion 6,“Filters.”
:AUTO <b>
[:SENSe[1]]:AVERage:AUTO <b> Enable/disable auto filter
Parameters <b> = 0 or OFF Disable auto filter
1 or ON Enable auto filter
Query :AUTO? Query state of auto filter
Description With auto filter enabled, the instrument automatically selects filter settings
for current measurements. Heavy filtering is used for the low current ranges,
and less filtering as the current range increases. The auto filter settings are
listed in Tables 6-5, 6-6, and 6-7. For voltage measurements, auto filter sets
the repeat and moving count to one, and the median rank to zero. These set-
tings effectively disable the three filters.
When auto filter is disabled, the present count and rank settings for the three
filters are used for all measurement functions and ranges.
