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.
National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:
Significant cost savings compared to individual repair incidents
Fault location, diagnostics, and repair by NI any time the system product fails
All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications
NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.
Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
