The National Instruments SCXI-1194 is a quad 4x1 high-frequency unterminated multiplexing switch capable of switching signals from DC to 2.5 GHz. The characteristic impedance of the channels on this module is 50 Ω. The NI SCXI-1194 has a maximum voltage rating of 30 Vrms with a maximum switching current of 500 mA. It is well-suited for applications that require the routing of high-frequency signals inside automated test equipment (ATE) systems because it can switch signals with very low insertion loss. In addition, the excellent voltage standing-wave ratio (VSWR) and isolation parameters make this module the perfect choice in any system geared toward high-frequency applications. The SCXI-1194 also offers relay count tracking to help reduce unexpected system downtime.

Note: The bandwidth specification of a switch module is not an absolute specification and is determined by vendor standards. Although you can route higher-frequency signals through this switch module, they encounter more degradation than those at lower frequencies. To determine the best switch module for your application, review the insertion loss, VSWR, and isolation specifications of the product for the bandwidth of your application. For more information on choosing the right RF switch for your application, review the "Guide to Selecting an RF Switch" under the Resources tab.
