The National Instruments PXI-2598 is a dual-transfer switch module designed for routing RF or microwave signals in automated test applications. While designed to operate with less than 1 dB insertion loss up to 26.5 GHz, the NI PXI-2598 appears almost invisible to signals at much lower frequencies as well. Use the PXI-2598 for basic signal routing or inserting and removing components in a signal path. This module is also well-suited for passing high-order harmonics from RF upconverters, such as the NI PXI-5670 2.7 GHz RF vector signal generator, or routing multiple sources to RF downconverters, such as the NI PXI-5660 2.7 GHz RF vector signal analyzer.
