The PXI-2797<\/strong> is a PXI RF Multiplexer Switch Module<\/strong> from National Instruments<\/strong>, designed for high-frequency RF signal routing, microwave signal switching, automated RF testing, wireless validation, and modular PXI test systems. As a 40 GHz, 50 \u03a9, 6×1 terminated PXI RF multiplexer switch module<\/strong>, the NI PXI-2797 provides one terminated 6×1 multiplexer bank for routing RF and microwave signals in automated test applications. NI lists the PXI-2797 with part number 782357-01<\/strong>.<\/p>\n

The NI PXI-2797<\/strong> is useful for engineers who need to automate RF and microwave signal path selection in high-frequency test systems. It can be used to route signals between RF signal generators, spectrum analyzers, vector signal analyzers, RF upconverters, RF downconverters, filters, amplifiers, receivers, antennas, and devices under test. Compared with manual RF switching, the PXI-2797 allows RF paths to be controlled through software, making it suitable for repeatable test sequences, laboratory automation, and production RF testing.<\/p>\n

One of the main advantages of the PXI-2797 RF Multiplexer Switch Module<\/strong> is its terminated 6×1 multiplexer topology<\/strong>. The internal termination helps prevent high-power reflections that may occur when unused channels are left open. This is especially important in RF and microwave systems where reflected power can affect measurement accuracy, damage sources, or create unstable signal behavior. NI describes the PXI-2797 as a high-density terminated multiplexer module with a single 6×1 multiplexer bank.<\/p>\n

The National Instruments PXI-2797<\/strong> supports 50 \u03a9 RF signal routing up to 40 GHz<\/strong>, making it suitable for higher-frequency RF and microwave applications than 26.5 GHz switch modules. This bandwidth is useful for microwave component validation, high-frequency receiver testing, harmonic routing, RF downconverter input routing, source selection, and automated signal path switching. The PXI-2797 is also 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-2797<\/strong> is designed as a terminated multiplexer<\/strong>, which makes it useful when signal reflection control and source protection are important. Compared with unterminated switch modules, the terminated architecture provides better control over unused RF paths. This makes the PXI-2797 practical for microwave test environments where signal path quality, impedance matching, insertion loss, isolation, and repeatable switching are important.<\/p>\n

Technical listings describe the NI PXI-2797<\/strong> as a 6×1 terminated RF or microwave multiplexer switch module for automated test applications, with insertion loss under 1 dB<\/strong> and operation up to 40 GHz<\/strong>. Distributor data also lists it as a 40 GHz, 6-channel, electromechanical relay, 6×1 PXI RF multiplexer switch module<\/strong> with 30 VAC<\/strong> switching voltage.<\/p>\n

In system integration, the PXI-2797 PXI RF Multiplexer 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-2797<\/strong> is suitable for applications such as RF signal routing, microwave signal switching, wireless device testing, RF source selection, harmonic routing, receiver testing, RF downconverter input routing, production RF test, and automated measurement systems. Its terminated 6×1 architecture is especially useful when multiple high-frequency RF paths need to be switched to one common measurement or stimulus channel while maintaining termination on unused paths.<\/p>\n

Overall, the NI PXI-2797 PXI RF Multiplexer Switch Module<\/strong> is a high-frequency RF switching solution for PXI-based automated test systems. With its 40 GHz bandwidth<\/strong>, 50 \u03a9 impedance<\/strong>, 6×1 terminated multiplexer topology<\/strong>, electromechanical relay design, and software-controlled switching capability, the PXI-2797 is well suited for RF signal routing, microwave validation, production testing, and modular PXI test applications.<\/p>","protected":false},"excerpt":{"rendered":"
