The PXI-2799<\/strong> is a PXI RF Relay Module<\/strong> from National Instruments<\/strong>, designed for RF signal routing, microwave signal switching, component insertion, automated RF testing, and modular PXI test systems. As a 40 GHz, 50 \u03a9, dual SPDT PXI RF relay module<\/strong>, the NI PXI-2799 provides two independent single-pole double-throw RF relay paths in one PXI module. NI lists the PXI-2799 with part number 782359-01<\/strong>.<\/p>\n

The NI PXI-2799<\/strong> is useful for engineers who need flexible RF or microwave path control in automated test systems. It can be used for basic signal routing, inserting or removing components in a signal path, selecting RF sources, switching between measurement paths, or configuring different test conditions through software. Compared with manual RF switching, the PXI-2799 helps improve test repeatability, reduce operator error, and simplify automated RF test sequences.<\/p>\n

One of the main advantages of the PXI-2799 RF Relay Module<\/strong> is its dual SPDT topology<\/strong>. Each SPDT relay can switch one common RF path between two selectable paths, giving users flexible signal routing options. This topology is useful for source selection, signal path switching, component insertion, bypass routing, calibration path switching, and compact RF switch network design.<\/p>\n

The National Instruments PXI-2799<\/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. This frequency range is useful for RF front-end testing, microwave component validation, receiver testing, RF source routing, harmonic testing, and automated signal path selection. NI also describes the PXI-2799 as suitable for passing high-order harmonics from PXI RF Signal Upconverter modules or routing multiple sources to PXI RF Signal Downconverter modules.<\/p>\n

The PXI-2799<\/strong> uses electromechanical relay switching and is designed for automated RF and microwave test environments. Its high-frequency SPDT architecture makes it practical for systems that require clean switching paths, repeatable performance, and compact PXI-based RF routing. It is especially useful when two independent RF switching paths are required in one module.<\/p>\n

Another useful feature of the NI PXI-2799<\/strong> is onboard relay count tracking<\/strong>. This feature helps users monitor relay usage and estimate relay lifetime, reducing the risk of unexpected downtime in automated test systems. Relay count tracking is especially valuable in production environments where RF switch modules may operate repeatedly over long periods.<\/p>\n

In system integration, the PXI-2799 PXI RF Relay 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-2799<\/strong> is suitable for applications such as RF signal routing, microwave signal switching, RF component insertion, bypass path switching, calibration path switching, harmonic routing, receiver testing, RF downconverter input routing, production RF test, and automated measurement systems. Its dual SPDT design is especially useful when two independent high-frequency RF switching paths are needed in one PXI slot.<\/p>\n

Overall, the NI PXI-2799 PXI RF Relay Module<\/strong> is a flexible high-frequency RF and microwave switching solution for PXI-based automated test systems. With its 40 GHz bandwidth<\/strong>, 50 \u03a9 impedance<\/strong>, dual SPDT relay topology<\/strong>, relay count tracking, electromechanical switching, and software-controlled operation, the PXI-2799 is well suited for RF signal routing, microwave validation, component insertion, production testing, and modular PXI test applications.<\/p>","protected":false},"excerpt":{"rendered":"
