MEASurement Instructions

MEASure[1|2][:SCALar][:POWer:AC]:DIFFerence? [<expected_value>[,<resolution>[,<source list>]]]

HP E4418B/E4419B Programming Guide 2-55

Example

1. The mnemonic DEF means DEFault. This is not equivalent to the DEFault

parameter used in the command sub-systems. The parameters must be entered in

the speciﬁed order. If parameters are omitted, they will default from the right.

The parameter DEFault is used as a place holder. Specifying

DEF leaves the

parameter value unchanged.

2. When the measurement result is linear this parameter represents the number

of signiﬁcant digits. When the measurement result is logarithmic 1 to 4

represents a resolution of 1, 0.1, 0.01 and 0.001 respectively.

source list This channel list speciﬁes between

which channels the difference is

calculated.

If unspeciﬁed and the current

window setup is a difference

measurement then this difference

setup is used, otherwise it defaults

to channel A-B.

(@1),(@2)

(@2),(@1)

MEAS2:DIFF? This command queries the

difference measurement on the

lower window.
