CDMA2000 Signaling

User Manual 1173.9511.02 ─ 12
The R&S
CMW supports only spreading rate 1 (also called 1x). For 1x the forward as
well as the reverse channel use a single direct-sequence spread carrier with a chip
rate of 1.2288 Mcps.
The R&S
CMW supports several CDMA2000 signaling modulation schemes, to be
selected as radio configuration:
●
O-QPSK
: Supports cdmaOne connections (RC 1 and 2).
●
H-PSK
: Supports CDMA2000 connections (RC 3, 4 and 5).
4.2.13 Band Classes
The band classes for CDMA2000 forward and reverse signals are defined in 3GPP2
C.S0057-C. Each band class contains a number of carrier frequencies and corre-
sponding channel numbers.
The tables below list the supported band classes with the corresponding channel num-
bers and the formulas for calculation of center frequencies from channel numbers.
