Chapter 2 Using the SCXI-119X

Expanding the RF Multiplexer

Figure2-4 shows how to expand the SCXI-119X by cascading stages

together. In the specific case of Figure 2-4, the module is used to create a

13 to 1 multiplexer with a two-stage architecture. You can cascade several

modules to provide even larger multiplexers. Cascading multiplexers

increases insertion loss, creates propagation delays, and may have other RF

effects.
