The PXI-2547<\/strong> is a PXI RF Multiplexer Switch Module<\/strong> from National Instruments<\/strong>, designed for RF signal routing, automated RF testing, wireless validation, RF path selection, and modular PXI test systems. As a 2.7 GHz, 50 \u03a9, 8×1 PXI RF multiplexer switch module<\/strong>, the NI PXI-2547 allows users to route multiple RF input paths to a single common output path, or route one RF source to multiple test paths depending on system configuration. NI lists the PXI-2547 with part number 778572-47<\/strong>.<\/p>\n

The NI PXI-2547<\/strong> is useful for engineers who need to switch a large number of RF signals in automated test systems. It can be used to route signals between RF signal generators, spectrum analyzers, vector signal analyzers, devices under test, antennas, filters, amplifiers, receivers, and other RF components. Compared with manual RF switching, the PXI-2547 allows RF signal paths to be controlled through software, making it suitable for repeatable test sequences, production validation, and laboratory automation.<\/p>\n

One of the main advantages of the PXI-2547 RF Multiplexer Switch Module<\/strong> is its 8×1 multiplexer topology<\/strong>. Compared with 4×1 RF multiplexer modules, the PXI-2547 provides a higher channel count, making it ideal for systems that need to switch several RF signals or connect multiple devices under test to one RF analyzer channel. This higher channel density helps reduce the number of switch modules required in a PXI chassis and improves system integration efficiency.<\/p>\n

The National Instruments PXI-2547<\/strong> supports 50 \u03a9 RF signal routing up to 2.7 GHz<\/strong>. This frequency range makes it suitable for many RF and wireless test applications, including communication device validation, RF front-end testing, filter testing, amplifier testing, antenna path switching, receiver testing, and automated RF signal routing. The module also provides strong insertion loss, VSWR, and isolation performance to help minimize signal degradation during RF switching.<\/p>\n

The PXI-2547<\/strong> is especially suitable for PXI-based systems where multiple RF devices or signal paths need to be connected to a single measurement channel. For example, engineers can use it to switch multiple DUT outputs into one RF analyzer, select between different antenna paths, route multiple RF sources, or automate RF path selection during production testing. Its 8×1 configuration provides more switching flexibility than lower-channel RF multiplexers while keeping the system compact.<\/p>\n

Another useful feature of the NI PXI-2547<\/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-2547 PXI RF Multiplexer Switch Module<\/strong> installs into a compatible PXI or PXI hybrid chassis and can be used with other PXI instruments such as RF signal generators, spectrum analyzers, vector signal transceivers, digitizers, source measure units, and data acquisition modules. This allows engineers to build compact automated RF test systems with software-controlled RF signal routing.<\/p>\n

The PXI-2547<\/strong> is suitable for applications such as RF signal routing, wireless device testing, RF path selection, antenna switching, amplifier testing, filter validation, receiver testing, production RF test, and automated measurement systems. Its 8×1 architecture makes it especially useful when many RF signal paths need to be switched to one common measurement or stimulus channel.<\/p>\n

Overall, the NI PXI-2547 PXI RF Multiplexer Switch Module<\/strong> is a practical RF switching solution for PXI-based automated test systems. With its 2.7 GHz bandwidth<\/strong>, 50 \u03a9 impedance<\/strong>, 8×1 multiplexer topology<\/strong>, relay count tracking, and software-controlled switching, the PXI-2547 is well suited for RF signal routing, wireless validation, production testing, and modular PXI test applications.<\/p>","protected":false},"excerpt":{"rendered":"
