naling application and the resulting reverse signal can be measured using the TX mea-
surement.
To link the measurement to the signaling application, the combined signal path sce-
nario must be activated (see
). The signal routing and analyzer
settings are then controlled by the signaling application. The TX measurement displays
the corresponding signaling settings instead of its own settings. The configurable sig-
nal routing and analyzer settings of the signaling application can be modified both via
the measurement GUI and via the GUI of the signaling application. To configure the
signal routing and analyzer settings via remote commands, the commands of the sig-
naling application have to be used. For a command mapping table, see
"Combined Signal Path Commands"
To synchronize the measurement to the signaling application, select a trigger signal
provided by the signaling application as trigger source:
●
For multi-evaluation measurements the super frame trigger is recommended.
●
For OLTR measurements the "Event" trigger of the signaling application has to be
used
5.2.4 Multi Evaluation List Mode
The CDMA2000 multi evaluation list mode requires option R&S CMW-KM012. In this
mode the multi/evaluation measurement interval is subdivided into segments, accord-
ing to the expected nominal power and frequency steps of the Mobile Station (MS)
under test.
The test signal that the R&S
CMW provides in list mode can be used e.g. for fast
receiver or power meter adjustments over a wide range of channels and powers.
5.2.4.1
Measurement Principle
Each segment contains an integer number of Power Control Groups (in following called
slots) and is measured at constant analyzer settings (i.e. at constant expected nominal
power and RF frequency). The figure
shows a series of four segments with differ-
ent lengths, powers and frequencies. Orange rectangles depict measured slots.

The R&S
CMW supports up to 10000 measured CDMA2000 slots, with up to 1000
slots per segment. In list mode the R&S
CMW can measure channel power, modula-
tion and spectrum results. It is possible to enable or disable the measured quantities
