The PXIe-2746<\/strong> is a PXI RF Multiplexer Switch Module<\/strong> from National Instruments<\/strong>, designed for RF signal routing, automated RF testing, production validation, wireless device testing, and modular PXI Express test systems. As a 2.7 GHz, 50 \u03a9, quad 4×1 PXI RF multiplexer switch module<\/strong>, the NI PXIe-2746 provides four independent 4×1 RF multiplexer banks in one PXIe module. NI lists the PXIe-2746 with part number 780587-46<\/strong>.<\/p>\n

The NI PXIe-2746<\/strong> is useful for engineers who need to switch many RF signal paths in automated test systems. It can be used to route signals between RF signal generators, spectrum analyzers, vector signal analyzers, RF components, filters, amplifiers, antennas, receivers, and devices under test. Compared with manual RF switching, the PXIe-2746 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 PXIe-2746 RF Multiplexer Switch Module<\/strong> is its quad 4×1 multiplexer topology<\/strong>. This configuration gives users four separate RF switching banks in a single PXIe module, which is useful for systems that require switching a large number of RF signals. NI specifically describes the PXIe-2746 as well suited for test systems that need to switch several devices under test to a single RF analyzer channel.<\/p>\n

The National Instruments PXIe-2746<\/strong> supports 50 \u03a9 RF signal routing up to 2.7 GHz<\/strong>. This frequency range makes it suitable for RF and wireless test applications such as RF front-end testing, communication device validation, receiver testing, amplifier testing, filter validation, antenna path switching, and automated RF signal routing. Distributor technical data also lists the PXIe-2746 as a quad 4×1 electromechanical RF multiplexer switch module<\/strong> with 500 mA<\/strong> switching current and 30 V<\/strong> maximum switching voltage.<\/p>\n

The PXIe-2746<\/strong> is especially suitable for production RF test systems where multiple DUTs or signal paths need to be connected to one or more measurement channels. Engineers can use it to switch multiple DUT outputs into an RF analyzer, select RF signal paths, automate receiver testing, or build compact RF switch networks inside a PXI Express chassis. Its quad-bank architecture helps reduce the number of separate switch modules required in a test system.<\/p>\n

Another useful feature of the NI PXIe-2746<\/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 PXIe-2746 PXI RF Multiplexer Switch Module<\/strong> installs into a compatible PXI Express chassis and can be used with RF signal generators, spectrum analyzers, vector signal transceivers, digitizers, source measure units, data acquisition modules, and other PXI\/PXIe instruments. Apex Waves also notes that the PXIe-2746 can save RF path calibration details in NI Switch Executive, which is useful for maintaining calibrated RF paths in automated systems.<\/p>\n

The PXIe-2746<\/strong> is suitable for applications such as RF signal routing, wireless device testing, RF path selection, receiver testing, amplifier testing, filter validation, production RF test, and automated measurement systems. Its quad 4×1 architecture is especially useful when multiple RF signal groups need to be switched inside one compact PXIe module.<\/p>\n

Overall, the NI PXIe-2746 PXI RF Multiplexer Switch Module<\/strong> is a practical high-density RF switching solution for PXI Express automated test systems. With its 2.7 GHz bandwidth<\/strong>, 50 \u03a9 impedance<\/strong>, quad 4×1 multiplexer topology<\/strong>, electromechanical relays, relay count tracking, and software-controlled switching, the PXIe-2746 is well suited for RF signal routing, wireless validation, production testing, and modular PXI Express test applications.<\/p>","protected":false},"excerpt":{"rendered":"
