Mobile Station (MS) is able to decode the forward channel and can perform synchroni-
zation.
The following sections provide background information about the properties of the
CDMA2000 forward link signal. If your focus is on operation of the instrument and you
have already a basic knowledge of the forward link signal, you may also skip these
sections and continue reading with the
GUI Reference . The GUI Reference provides
links to the background information where required.

6.2.1 Test Setup
The device under test (DUT) can be connected to one of the bidirectional RF connec-
tors RF 1 COM or RF 2 COM at the front panel of the R&S
CMW. No additional cabling
and no external trigger is needed. The input level ranges of all RF COM connectors are
identical.
The RF connection between the tester and the DUT carries the forward signal:
●
The R&S CMW transmits the forward (base station) signal to which the DUT can
synchronize in order to perform registration and establish the connection. The for-
ward signal is used to transfer signaling messages and user data to the DUT.

6.2.2 Band Classes
The band classes for CDMA2000 forward signals are defined in specification 3GPP2
C.S0057-C. Each band class contains a number of carrier frequencies and corre-
sponding channel numbers.
The table below lists the supported band classes with the corresponding channel num-
bers and the formulas for calculation of center frequencies from channel numbers.
