The SR3452 V2, shown in Figure 2-2, provides the core emulation of a CDMA network. Use the SR3452 V2 in a single instrument configuration or a dual instrument configuration. When used in the single instrument configuration, the SR3452 V2 emulates one BSC on a single RF carrier. In a dual instrument configuration, a second RF carrier is available to allow emulation of a second BSC. In either case, up to six independent sectors are emulated. Each of these sectors can provide a full complement of code channels. As an option, a SR3462 1xEV Rev0/RevA Network Emulator can be added to a single or dual SR3452 V2 configuration to provide either a single RF to operate in 1X or EV-DO mode or two simultaneous RF channels to deliver both 1X and EV-DO network emulation in a single configuration.
