Repeat fi lter commands
:REPeat:COUNt <n>
[:SENSe[1]]:AVERage:REPeat:COUNt <n> Set repeat fi lter count
Parameters
<n> = 1 to 100 Specify repeat fi lter count
DEFault 1
MINimum 1
MAXimum 100
Query
:COUNt? Query fi lter count
:COUNt? DEFault Query the *RST default fi lter count
:COUNt? MINimum Query the lowest allowable fi lter count
:COUNt? MAXimum Query the largest allowable fi lter count
Description
This command is used to specify the repeat fi lter count. In general, the fi lter
count is the number of readings that are acquired and stored in the fi lter
buffer for the averaging calculation. Each aquired group of readings yields a
single
fi ltered reading. The larger the fi lter count, the more fi ltering that is
performed.
:REPeat[:STATe] <b>
[:SENSe[1]]:AVERage:REPeat[:STATe] <b> Enable/disable repeat fi lter
Parameters
<b> = 0 or OFF Disable repeat fi lter
1 or ON Enable repeat fi lter
Query
[:STATe]? Query state of repeat fi lter
Description
This command is used to enable or disable the repeat fi lter. When enabled,
voltage, current, and resistance readings are fi ltered according to how the
repeat fi lter is con fi gured. When disabled, the repeat fi lter stage is bypassed.
Median fi lter commands
:MEDian:RANK <NRf>
[:SENSe[1]]:MEDian:RANK <NRf> Set median fi lter rank
Parameters
<NRf> = 0 to 5 Specify rank value for median fi lter
RANK? Query median fi lter rank
Description
The median fi lter is used to pass the “ middle-most ” reading from a group of
readings that are arranged according to size. This command is specify the
rank, which determines the number of reading samples for the
fi lter process.
The number of reading samples are determined as follows:
Sample readings = 2n + 1
Where; n is the selected rank (0 to 5).
