National Instruments: High-performance VSA moves into PXIe realm

Traditionally, the highest performing instruments have always been monolithic, box instruments, because trying to get high-speed performance from a rack of card-modules connected by a copper backplane has been a stumbling block. The NI PXIe-5665 14-GHz three-stage RF vector signal analyzer (VSA) upsets that tradition by outperforming box VSAs in several areas, at the same time significantly reducing the cost of such instrumentation.

The modulular VSA’ exceptionally low phase noise of −129 dBc/Hz at a 10-kHz offset at 800 MHz, and an average noise level of −165 dBm/Hz, are backed by other high-performance specifications such as an industry’s best third-order intercept point of 24 dBm with an absolute amplitude accuracy of ±0.10 dB, as well as error vector magnitude of 0.33% for a 256-QAM modulated signal.

The VSA has a multicore computing architecture and uses NI LabVIEW to employ its parallel programming capabilities. It also offers peer-to-peer data streaming for signal processing and a flexible MIMO architecture for phase-coherent measurements. Priced starting at $49,999, typical configurations cost about a third less then monolithic instruments.
