The PXI-2798<\/strong> is a PXI Transfer Switch Module<\/strong> from National Instruments<\/strong>, designed for RF signal routing, microwave signal switching, automated RF testing, component insertion, and modular PXI test systems. As a 40 GHz, 50 \u03a9, dual-transfer PXI transfer switch module<\/strong>, the NI PXI-2798 provides software-controlled RF and microwave switching for automated test applications. NI lists the PXI-2798 with part number 782358-01<\/strong>.<\/p>\n

The NI PXI-2798<\/strong> is useful for engineers who need to automate RF or microwave signal paths in a PXI-based test system. It can be used for basic signal routing, inserting or removing components in a signal path, routing RF sources, switching between measurement paths, or configuring different test conditions through software. Compared with manual RF switching, the PXI-2798 helps improve repeatability, reduce operator error, and simplify automated RF test sequences.<\/p>\n

One of the main advantages of the PXI-2798 Transfer Switch Module<\/strong> is its dual-transfer switch topology<\/strong>. A transfer switch is useful when two RF signal paths need to be exchanged, inserted, bypassed, or rerouted in a controlled way. This makes the PXI-2798 suitable for applications where engineers need to switch between calibration and measurement paths, insert RF components into a signal chain, or change microwave routing without manually reconnecting cables.<\/p>\n

The National Instruments PXI-2798<\/strong> supports 50 \u03a9 RF and microwave signal routing up to 40 GHz<\/strong>, making it suitable for high-frequency RF and microwave test applications. NI describes the module as operating with less than 1 dB insertion loss up to 40 GHz<\/strong>, and notes that it is suitable for passing high-order harmonics from RF upconverters or routing multiple sources to RF downconverters.<\/p>\n

The PXI-2798<\/strong> is especially useful in automated RF and microwave systems where signal paths must be changed repeatedly and reliably. Engineers can use it for RF front-end testing, microwave component validation, receiver testing, RF source routing, harmonic testing, calibration path switching, component bypass testing, and automated signal path selection.<\/p>\n

In system integration, the PXI-2798 PXI Transfer Switch Module<\/strong> installs into a compatible PXI or PXI hybrid chassis and can be used with RF signal generators, spectrum analyzers, vector signal transceivers, RF upconverters, RF downconverters, digitizers, source measure units, and other PXI instruments. This allows engineers to build compact automated RF and microwave test systems with software-controlled signal routing.<\/p>\n

The PXI-2798<\/strong> is suitable for applications such as RF signal routing, microwave signal switching, RF component insertion, calibration path switching, harmonic routing, receiver testing, RF downconverter input routing, production RF test, and automated measurement systems. Its dual-transfer design is especially useful when RF paths must be exchanged, inserted, bypassed, or reconfigured through software control.<\/p>\n

Overall, the NI PXI-2798 PXI Transfer Switch Module<\/strong> is a high-frequency RF and microwave switching solution for PXI-based automated test systems. With its 40 GHz bandwidth<\/strong>, 50 \u03a9 impedance<\/strong>, dual-transfer switch topology<\/strong>, low insertion loss, and software-controlled operation, the PXI-2798 is well suited for RF signal routing, microwave validation, component insertion, production testing, and modular PXI test applications.<\/p>","protected":false},"excerpt":{"rendered":"
