The National Instruments SCXI-1193 is a high-density RF relay switching module for SCXI systems, designed for programmable routing of high-frequency signals. It provides 32 RF channels with a nominal 50 Ω characteristic impedance and supports multiple configurations, including quad 8×1 multiplexers, dual 16×1 multiplexers, a single 32×1 multiplexer, terminated multiplexer configurations, and flexible sparse-matrix arrangements. The module operates from DC to 500 MHz and is designed for integration with high-frequency test and measurement equipment. NI identifies the SCXI-1193 as a discontinued product, making it particularly suitable for maintenance, replacement, and continued operation of legacy SCXI test systems.
