Chapter 2 Using the SCXI-119X
© National Instruments Corporation 2-9 SCXI-1190/1191/1192 User Manual
Figure 2-7 shows one possible expansion using two SCXI-1192 modules.
In this case, the switches on two SCXI-1192 modules are interconnected to
create a 2 × 4 matrix. Multiple configurations are possible using one or
more SCXI-1192 modules.
Note
Cascading switches increases insertion loss, creates propagations delays, and can
have other RF effects.
