Expanding its modular PXI line, National Instruments has added new PXI and SCXI RF multiplexing switch modules capable of routing signals ranging from DC to 5 GHz. They are suitable for accurate RF signal routing in telecommunications, military/aerospace and automated test applications.

The 5 GHz PXI-2595 and SCXI-1195 switches and the 2.5 GHz PXI-2594 and SCXI-1194 switches offer excellent VSWR, isolation and insertion loss specifications to retain signal integrity across their entire frequency range. All switches feature built-in relay count tracking for predictive maintenance of the module, reducing the potential for system downtime as the relays near the end of their rated lifetimes.

Engineers can use the PXI-2594 and PXI-2595 with PXI vector signal analyzers and generators to create a complete RF application in one PXI chassis. Furthermore, both PXI switches integrate with all NI PXI modular instruments, including digitizers, digital multimeters, power supplies and arbitrary waveform generators, to help create a complete functional test system in one platform.

When combined with the supplier’s USB switch mainframes, these SCXI switches form a cost-effective, plug-and-play solution that easily integrates with external RF equipment and takes advantage of the flexibility and ease of use of USB.
