While designed to operate with less than 1 dB insertion loss up to 26.5 GHz, they appear almost invisible to signals at much lower frequencies as well. Use the NI PXI-2597 terminated multiplexer when high-power signal reflections are a concern and 50 terminations are required. The PXI-2596 offers a higher-density, unterminated option with dual 6x1 multiplexer banks in the same module. The PXI-2598 and PXI-2599 operate as transfer switches and SPDT relays, respectively, for basic signal routing or inserting and removing components in a signal path. These modules are 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. All National Instruments PXI switch modules are shipped with NI-SWITCH, an IVI-compliant driver offering complete functionality for all switch modules. For additional assistance in configuring, programming, and managing higher-channel-count switching systems, NI Switch Executive software offers an easy-to-use, intelligent switch management and visual routing environment. With the latest version of NI Switch Executive, you can store calibration information for your RF/microwave switch routes on a per-path basis. Use the NI-SWITCH Soft Front Panel for simple relay operations or debugging switch code/execution. Ω Relay Count Tracking The switches count relay closures on each of their individual relays. Relay counts are incremented each time a relay is actuated. You can programmatically retrieve the counts, stored on board the modules, and use them for predictive maintenance to reduce unexpected system downtime. Signal Connectivity Options The PXI-2596, PXI-2597, PXI-2598, and PXI-2599 all use standard SMA connectors for signal connections. National Instruments offers two semirigid SMA cables (0.15 and 0.45 cm) that are acceptable for many RF/microwave signals. There are also many custom cable vendors on the market that can meet your exact cable length, performance, and connector requirements. Please visit ni.com/switches for a list of third-party cable vendors.
