NI VST offers 2GHz bandwidth and continuous frequency coverage
NI’s most versatile and capable vector signal transceiver (VST) is the third generation PXIe-5842 VST. The company claimed it is the only VST to offer continuous frequency coverage from 50MHz to 23GHz, to doubles the available instantaneous bandwidth from 1GHz on the previous generation to 2GHz and to provide best-in-class RF performance on key metrics such as error vector magnitude (EVM) and average noise density.
The increased complexity of technologies, standards and frequencies, coupled with pressures for faster time to market, have created a demand for NI’s products to cover all bands in a single instrument. The PXIe-5842 is the highest-performing PXI VST instrument available, according to the company.
EVM performance has been improved by 3dB for key Wi-Fi 7 and 5GNR waveforms. The PXIe-5842’s low-cost, scalable approach means it can offer a single instrument that can be configured to 8GHz for sub-8 cellular and Wi-Fi applications, 12GHz for cellular and connectivity applications, and 23GHz for applications that require the ultimate flexibility on frequency spectrum ranging from VHF to Ku for applications such as radar target simulation and spectrum monitoring in electronic warfare and satellite communications.
“The PXIe-5842 can be configured to offer GHz, two times the coverage of competitor’s models. And at 2GHz bandwidth, the PXIe-5842 provides a 67 per cent increase in bandwidth over currently available models, giving our customers the competitive advantage,” said Chen Chang, strategic business development director, NI.
The PXIe-5842 can measure 802.11be EVM performance of more than –49dB, for standard compliant test cases. Its scalability and simplified test benches offer customers one instrument and one connection.
Additional key features include: continuous frequency coverage from 50MHz to 23GHz; 2GHz instantaneous bandwidth; direct RF path below 1.75GHz; baseband conditioning modes optimised for wide bandwidth or high dynamic range; MGT connectors for streaming at full data rate (Q1 2023); increasing test coverage capability with best-in-class VST performance; combined multiple VSTs in one integrated PXIe system for MIMO applications, allowing for up to 4×4 MIMO configuration into one 18-slot chassis; common software tools to PXIe-583x; and PXIe-5841 for a seamless upgrade experience.
From data and automation to research and validation, NI provides the tailored, software-connected systems engineers and enterprises need to ‘engineer ambitiously’ every day.
