Using the SCXI-119
X
This chapter contains a functional overview, safety instructions, and
connection possibilities of the SCXI-119X multiplexer module.
Functional Overview
The SCXI-119X modules are general-purpose, quad 4-channel,
high-bandwidth multiplexing switches. The SCXI-1190 uses single-pole
double-throw, high-bandwidth relays capable of switching signals from
DC to 1.3 GHz. Functionally identical, the SCXI-1191 has a bandwidth of
DC to 4 GHz. Figure 2-1 illustrates the key functional components of the
SCXI-119X multiplexer module.
