 Data Sheet |
Configure System 
The National Instruments SCXI-1195 is a quad 4x1 high-frequency unterminated multiplexing switch capable of switching signals from DC to 5 GHz. The characteristic impedance of the channels on this module is 50 Ω. The NI SCXI-1195 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 towards high-frequency applications.
