Overview
The NI PXIe-5842 is NI's third-generation PXI vector signal transceiver (VST). A VST combines an RF signal generator, an RF signal analyzer and a powerful user-programmable FPGA onto a single PXI module — an approach NI pioneered in 2012 and has refined ever since.
The PXIe-5842 is the first VST to offer continuous frequency coverage from 30 MHz up to 26.5 GHz, and it doubles the instantaneous bandwidth of previous models to 4 GHz while improving key RF metrics such as error vector magnitude (EVM) and average noise density. A 54 GHz frequency extension is available.
The instrument pairs the PXIe-5842 module with the high-performance PXIe-5655 dual LO synthesizer. Up to four PXIe-5842 VSTs can be fitted into a single 18-slot PXI chassis, making it a scalable foundation for modern wireless and RF validation.
Key Benefits
Continuous coverage: 30 MHz to 26.5 GHz (to 54 GHz with extension). Wide bandwidth: up to 4 GHz instantaneous. Best-in-class EVM: vector-tested for Wi-Fi 7 and 5G NR. Scalable: up to four VSTs per 18-slot PXI chassis.
Applications
5G NR and Wi-Fi 7 device validation, radar and satellite RF test, semiconductor RF characterisation, and modular automated test systems.
