PXI VSA covers 14 GHz with top specs

摘要

The NI PXIe-5665 14-GHz three-stage RF vector signal analyzer (VSA) is said to deliver the best phase-noise and dynamic-range performance of any VSA, including traditional rack-and-stack instruments. Because the VSA is based on PXIe, it can also deliver measurement speeds up to 20 times faster than box instruments - and do so at a lower cost. To extend the capabilities of the earlier 3.6 GHz version to 14 GHz, the VSA employs the 20 Hz to 14-GHz NI PXIe-5605 downconverter, along with the NI PXIe-5653 local oscillator synthesizer and the NI PXIe-5622 150-MSample/s intermediate frequency (IF) digitizer.
