NI launches third generation vector signal transceiver


NI has launched its third generation PXIe-5842 vector signal transceiver (VST).

According to NI it is the onlyvector signal transceiver (VST) to offer continuous frequency coverage from 50MHz all the way up to 23GHz, doubles the available instantaneous bandwidth from 1GHz, on the previous generation, to 2GHz and provides best-in-class RF performance on key metrics such as Error Vector Magnitude (EVM) and Average Noise Density.

The VST is a response to changing wireless technologies and increased complexity, standards and frequencies, while it should help engineers meet demands for faster time to market in a single instrument, said NI.

The PXIe-5842 is the highest-performing PXI VST instrument available. EVM performance has been improved by 3dB for key Wi-Fi 7 and 5GNR waveforms. The PXIe-5842’s low cost, scalable approach is now the only PXI product that can offer a single instrument that can be configured to 8 GHz for sub-8 cellular and Wi-Fi applications, 12 GHz for cellular and connectivity applications, and 23 GHz 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.

Chen Chang, strategic business development director at NI said,  “We are excited to bring this revolutionary product to the wireless industry.

“The PXIe-5842 can be configured to offer 23 Gigahertz, two times the coverage of competitor’s models. And at 2 Gigahertz bandwidth, the PXIe-5842 provides a 67% increase in bandwidth over currently available models, giving our customers the competitive advantage.”

While traditional RF box instrumentation can be bulky, expensive, and lacking versatility. The PXIe-5842 offers high measurement accuracy and can measure 802.11be Error Vector Magnitude (EVM) performance of more than –49 dB, for standard compliant test cases.
