Section 14: SCPI command reference

This command is used to specify the median rank for volts, amps, ohms, and coulombs.

[:SENSe[1]]:VOLTage[:DC]:MEDian:RANK <NRf>

[:SENSe[1]]:CURRent[:DC]:MEDian:RANK <NRf>

[:SENSe[1]]:RESistance:MEDian:RANK <NRf>

[:SENSe[1]]:CHARge:MEDian:RANK <NRf>

The number of sample readings used for the median calculation is determined by the selected range

(1 to 5) as follows:

Sample readings = (2  R) + 1

Where: R is the selected range (1 to 5)

For example, a rank of 5 uses the last 11 readings to determine the median;

(2  5) + 1 = 11.

Each new reading replaces the oldest reading, and the median is then determined from the updated

sample of readings.
