MEASurement Instructions
MEASure[1|2][:SCALar][:POWer:AC]:RATio:RELative? [<expected_value>[,<resolution>[,<source
list>]]]
HP E4418B/E4419B Programming Guide 2-61
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 ratio is
calculated.
If unspecified and the current
window setup is a ratio
measurement then this ratio setup
is used, otherwise it defaults to
channel A/B.

MEAS:RAT:REL? This command queries the
relative ratio measurement on
the upper window.
