319Operating Manual 1176.7510.02 ─ 09
Results are provided for the TX channel and the number of defined adjacent channels
above and below the TX channel. If more than one TX channel is defined, the carrier
channel to which the relative adjacent-channel power values should be referenced
must be defined.
The measured power values for the TX and adjacent channels are also output as a
table in the second screen. Which powers are measured depends on the number of
configured channels, see "# of Adj Chan" on page 325.
For each channel, the following values are displayed:
Label Description
Channel Channel name as specified in the "Channel Settings" (see "Names" on page 329).
Bandwidth Configured channel bandwidth (see "Bandwidth" on page 327)
Offset Offset of the channel to the TX channel (Configured channel spacing, see "Spacing"
on page 328)
Power
(Lower/Upper)
The measured power values for the TX and lower and upper adjacent channels. The
powers of the transmission channels are output in dBm or dBm/Hz, or in dBc, relative
to the specified reference TX channel.
Retrieving Results via Remote Control
All or specific channel power measurement results can be retrieved using the
CALCulate<n>:MARKer<m>:FUNCtion:POWer:RESult? command from a remote
computer.
Alternatively, the results can be output as channel power density, i.e. in reference to
the measurement bandwidth (see CALCulate<n>:MARKer<m>:FUNCtion:POWer:
RESult:PHZ on page 703).
Furthermore, the measured power values of the displayed trace can be retrieved as
usual using the TRAC:DATA? commands (see TRACe<n>[:DATA]? on page 887). In
this case, the measured power value for each sweep point (max. 691) is returned.
Configuring and Performing Channel Power Measurements
Predefined standards contain the main measurement settings for standard measure-
ments. When such a standard is loaded, the required channel settings are automati-
cally set on the R&S FSVA/FSV. However, the settings can be changed, and measure-
ments with user-defined configurations are also possible.
Once the channels have been set up, other instrument settings such as the used filter
bandwidths, frequency span and detector and trace settings can be optimized automat-
ically (see "Adjust Settings" on page 331).
For an overview of the softkeys and menus see "Softkeys for Channel and Adjacent-
Channel Power Measurements" on page 324.
Selecting a Predefined Standard
Predefined standards contain the main measurement settings for standard measure-
ments. When such a standard is loaded, the required channel settings are automati-
cally set on the R&S FSVA/FSV.
