NI announces ‘industry leading’ rf vector signal analyser

According to the company, the NI PXIe-5665 features industry leading phase noise, average noise level, amplitude accuracy and dynamic range. Its PXI platform also facilitates peer to peer streaming - which includes a flexible multiple input as well as multiple output architecture for phase coherent measurements - and offers measurement speeds which NI claims are at least five times faster than traditional rack and stack instruments. "Not only is the NI PXIe-5665 the highest performing instrument in its class, it is available at a fraction of the cost of traditional rack and stack instruments," said Phil Hester, senior vice president of research and development at National Instruments. "The rf analyser combines high end performance with modular flexibility in a compact, affordable package, allowing engineers to use the same instrument from design to production." The company has also announced a new NI PXIe-5603 downconverter, NI PXIe-5653 local oscillator synthesiser and the NI PXIe-5622 150 MS/s intermediate frequency digitiser. The combination has been designed for spectrum and wideband vector signal measurements over a frequency range from 20Hz to 3.6GHz, with analysis bandwidths up to 50MHz. An onboard self calibration tool has been implemented to achieve an IF amplitude response of ±0.15dB and IF phase linearity of ±0.1 degree.
