MEASurement Instructions
MEASure[1|2][:SCALar][:POWer:AC]:RELative? [<expected_value>[,<resolution>[,<source list>]]]
Agilent E4418B/E4419B Programming Guide 2-53
Example
source list This is the channel on which the
command is implemented.
If unspecified the current window
setup is used. However, on the
Agilent E4419B, if the window
shows a ratio or difference
measurement, the upper window
defaults to channel A and the
lower window to channel B.

only)
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.
MEAS1:REL? -50DBM,2,(@2) This command queries the upper
window’s relative measurement of
channel B, using an expected
power level of -50 dBm and a
resolution setting of 2.
