High-performance RF VSA comes in PXI package

Said to offer performance that surpasses traditional rack-and-stack instrumentation, the PXIe-5665 3.6-GHz RF vector signal analyzer (VSA) features industry-leading phase noise (–129 dBc/Hz at a 10-kHz offset at 800 MHz), average noise level (–165 dBm/Hz), amplitude accuracy (±0.10 dB), and dynamic range (third-order intercept point is 24 dBm). With peer-to-peer streaming between on-bus PXI modules and a flexible MIMO architecture for phase-coherent measurements, the VSA can provide measurement speeds at least five times faster than traditional rack-and-stack instruments.

The VSA consists of three PXI modules: the PXIe-5603 downconverter and NI PXIe-5653 local oscillator synthesizer, both of which are just being introduced, and the PXIe-5622 150-Msample/s intermediate frequency (IF) digitizer. This combination can tackle spectrum and wideband vector signal measurements, providing analysis bandwidths up to 50 MHz over a 20-Hz to 3.6-GHz range.

A unique onboard self-calibration tool makes it possible to achieve an IF amplitude response of ±0.15 dB and IF phase linearity of ±0.1° for modulated signal analysis. With this accuracy error vector magnitude performance is less than 0.21% for a 256-QAM signal. The VSA can also be expanded for phase-coherent acquisition for MIMO test, as well as a 20-GHz/s scan rate and peer-to-peer streaming for efficient spectrum monitoring.

Operated in RF list mode, the instrument can deterministically step through a user-defined set of RF configurations using internal timing or an external trigger, thereby significantly reducing test time. (From $29,999 — available now.)
