Chapter 2 Using the SCXI-119X
SCXI-1190/1191 User Manual 2-6 www.ni.com
Expanding the RF Multiplexer
Figure 2-4 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.
