Figure 5-2. Typical XSAT Redundant System, with IF Transfer Switches
The standard RSU-5060 uses two 1:2 IF combiners/dividers to distribute the IF signals to the two
transceivers. As an option, the RSU-5060 can be provided with IF transfer switches (Figure 5-2).
This allows the user to access the offline transceiver from the TX/RX sample ports. These
switches are internal to the RSU and their positions are set to mirror the external TX/RX
switches.
