Installing and Configuring the
SCXI-119X
This manual describes the electrical and mechanical characteristics of the
SCXI-1190 (quad 1
× 4, 50 Ω, 1.3 GHz bandwidth) and SCXI-1191 (quad
1
× 4, 50 Ω, 4 GHz bandwidth) multiplexer modules, and the SCXI-1192
(8-channel, SPDT, 50
Ω, 18 GHz bandwidth) relay module for the SCXI
bus. It also contains information concerning their installation, operation,
and safety instructions.
About the SCXI-119X
This section summarizes the features and operation of the SCXI-119X
switch modules. In addition, refer to Appendix A,
for detailed specifications of the switch modules.
The SCXI-1190/1191 modules are 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-119X modules 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), and from DC to
18 GHz bandwidth (SCXI-1192). The characteristic impedance of the
channels is 50
Ω.
For the SCXI-1190, the maximum rated voltage of the switch is 24 V,
and the maximum rated current is 1 A at 24 V. For the SCXI-1191, the
maximum rated voltage of the switch is 30 V, and the maximum rated
current is 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.
