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
individually for each segment. Depending on the measured quantity, additional statisti-
cal values (average, minimum, maximum and standard deviation) are calculated for an
administrable number of slots (statistical length) at the beginning of the segment. The
"current" result of a segment refers to the last measured slot of the statistical length in
that segment (see figure
