PXIe-2543

Земля PXIe-2543 является PXI RF Multiplexer Switch Module от Национальные инструменты, designed for RF signal routing, wireless device testing, automated RF validation, semiconductor production testing, and modular PXI Express test systems. As a 6.6 GHz, 50 Ω, solid-state, dual 4×1 PXI RF multiplexer switch module, the NI PXIe-2543 provides two independent 4×1 RF multiplexer banks in one PXIe module. NI lists the PXIe-2543 with part number 780587-43.

Земля NI PXIe-2543 is useful for engineers who need fast and repeatable RF path switching in automated test systems. It can be used to route RF signals between signal generators, analyzers, receivers, amplifiers, filters, antennas, RF front-end modules, and devices under test. Compared with manual RF switching, the PXIe-2543 allows RF paths to be controlled through software, making it suitable for repeatable test sequences, laboratory automation, and high-volume production RF testing.

Одно из главных преимуществ PXIe-2543 RF Multiplexer Switch Module это его solid-state relay architecture. Unlike electromechanical RF relays, solid-state relays provide extremely fast switching speed and eliminate mechanical wear, which is important for production environments where switching operations occur continuously. NI states that the PXIe-2543 uses high-performance solid-state relays that provide fast switching time and virtually unlimited mechanical lifetime.

Земля National Instruments PXIe-2543 поддерживает 50 Ω RF signal routing up to 6.6 GHz, making it suitable for RF and wireless communication test applications. This frequency range is useful for RF front-end testing, wireless device validation, receiver testing, amplifier characterization, filter validation, antenna switching, multisite semiconductor testing, and automated RF signal routing. The module uses front-mounted SMA connectors, helping simplify RF cabling and instrument integration.

Земля PXIe-2543 uses a terminated dual 4×1 multiplexer topology, also described as a dual SP4T architecture. Each multiplexer bank can route one common RF path to four selectable RF channels while maintaining 50 Ω termination. NI notes that the module includes termination on every COM line and channel, helping reduce RF reflections and improve signal integrity.

Технические характеристики описывают NI PXIe-2543 as supporting a minimum input frequency of 10 MHz, characteristic impedance of 50 Ω, and maximum safe continuous RF power of +30 dBm when chassis power is on. The module also provides insertion loss below 7 dB up to 6.6 GHz, with typical insertion loss around 6.1 dB. Additional specifications include isolation up to 71 dB, VSWR around 1.60:1, and a switching operating time of approximately 76 μs.

Another advantage of the PXIe-2543 is its suitability for high-volume RF production testing. NI introduced the module specifically to improve RF test throughput and long-term repeatability in applications such as semiconductor testing and mobile device production. Its fast switching capability and solid-state architecture make it useful for multisite RF switching systems where durability and measurement consistency are important.
