NI PXI-2547

The National Instruments PXI-2547 is an 8x1 high-frequency multiplexer switch module suited for routing signals from DC to 2.7 GHz in 50 Ω RF applications. It can switch up to 30 Vrms or 500 mA at a maximum power rating of 10 W. The higher channel-count of the NI PXI-2547 makes it ideal for test systems that require the switching of a large number of RF signals, such as switching several devices under test to a single channel on the RF analyzer. The module also features excellent insertion loss, voltage standing-wave ratio (VSWR), and isolation parameters to minimize signal degradation; and its onboard relay-count-tracking feature can be used to predict relay lifetime and 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.
