Making the switch
NI has introduced four new 26.5 GHz PXI switch modules and a new version of the company’s Switch Executive switch management software.
Engineers now can use four new National Instruments 26.5 GHz PXI switch modules and the latest version of the company’s Switch Executive switch management software for PXI-based RF and microwave test applications.
The National Instruments PXI-2596, PXI-2597, PXI-2598 and PXI-2599 are multiplexers, SPDT relays and transfer switch modules designed for routing RF or microwave signals in automated test applications.
The new modules offer 26.5 GHz switching in multiple PXI configurations. Using microwave relays from Radiall, each module is designed to operate with less than 1 dB insertion loss up to 26.5 GHz, minimising impact on the test system and appearing almost invisible to signals at much lower frequencies.
They are useful for passing high-order harmonics from RF upconverters, such as the NI PXI-5671 2.7 GHz vector signal generator, or routing multiple sources to RF downconverters, such as the NI PXI-5660 2.7 GHz vector signal analyzer.
