NI PXI-2554

The National Instruments PXI-2554 is a 4x1 high-frequency unterminated multiplexing switch module capable of switching signals from DC to 2.5 GHz. The characteristic impedance of the channels on this module is 75 Ω. The NI PXI-2554 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 video 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 PXI-2554 also offers relay count tracking to help reduce unexpected system downtime.

Note: The bandwidth specification of a switch module, which is not an absolute specification, is determined by vendor standards. Although higher frequency signals can be routed through this switch module, they will encounter more degradation than those at lower frequencies. In order 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’ linked in the 'Resources' section of this page.
