Installing and Configuring theSCXI-119XThis manual describes the electrical and mechanicalcharacteristics ofthe
SCXI-1190(quad 1 × 4, 50 Ω, 1.3 GHz bandwidth) and SCXI-1191 (quad
1× 4,50Ω, 4GHz bandwidth) multiplexer modules, and the SCXI-1192
(8-channel, SPDT, 50 Ω, 18 GHz bandwidth) relay module forthe SCXI
bus. It also contains information concerning their installation, operation,
and safety instructions.
About the SCXI-119X
This sectionsummarizes the features and operationof the SCXI-119X
switch modules. In addition, refer to Appendix A, Specifications,
fordetailed specifications of the switchmodules.
The SCXI-1190/1191 modulesare general-purpose, quad 4-channel,
high-bandwidth multiplexing switches. The SCXI-1192 module is a
general-purpose, 8-channel, SPDT, high-bandwidth relay module.
The SCXI-119Xmodules use single-pole double-throw,high-bandwidth
relays capable of switching signals from DC to 1.3 GHz bandwidth
(SCXI-1190),from DC to 4 GHz bandwidth (SCXI-1191), a nd from DC to
18 GHz bandwidth (SCXI-1192). The characteristic impedance of the
channelsis 50 Ω.
Forthe SCXI-1190, the maxim um rated voltageof the switch is 24 V,
and the maximum rated current is 1 A at 24 V.For the SCXI-1191, the
maximum rated voltageof the switch is 30 V,and the maximum rated
currenti s 0.33 A at 30 V.For the SCXI-1192, the maximum rated voltage
of the switch is 30 V, and the maximum rated current is 2 A at 30 V.
See Appendix A, Specifications, for full specifications.
