The list mode can be activated/deactivated via command (see table above).
Global and list mode parameters
The RF settings (expected power, RF frequency) and most of the "Measurement Con-
trol" settings (step length, steps per segment, averaging lengths, enable/disable
results) are special list mode settings. The R&S
CMW ignores the corresponding "multi
evaluation" parameters. All other settings are taken from the multi evaluation measure-
ment, e.g.:
●
Measure on Exception

Some "Modulation" and "Spectrum" settings

3.2.6 Reverse Signal Properties
This section provides the following background information, referenced from other sec-
tions.
3.2.6.1
Band Classes
The operating bands for 1xEV-DO reverse signal are defined in 3GPP2 C.S0057-C.
Each band class contains a number of carrier frequencies and corresponding channel
numbers.
The table below lists all band classes with the corresponding channel numbers and the
formulas for calculation of center frequencies from channel numbers. The band classes
are grouped according to their frequencies (450 / 800 / 1900).
