National Instruments Releases PXI RF Vector Signal Analyzer

By DE Editors

National Instruments has introduced the NI PXIe-5665, a 3.6 GHz RF vector signal analyzer (VSA) that delivers RF performance in a cost-effective PXI form factor. The new VSA features phase noise, average noise level, amplitude accuracy and dynamic range. The VSA’s PXI platform also facilitates peer-to-peer streaming; includes a flexible multiple input, multiple output (MIMO) architecture for phase-coherent measurements; and offers fast measurement speeds.

“Not only is the NI PXIe-5665 VSA the highest performing instrument in its class, but it is available at a fraction of the cost of traditional rack-and-stack instruments,” says Phil Hester, senior vice president of research and development at National Instruments. “Because our new PXI RF analyzer combines high-end performance with modular flexibility into one compact, affordable package, engineers now can use the same instrument from design to production.”

The VSA combines the new NI PXIe-5603 downconverter with the new NI PXIe-5653 local oscillator synthesizer and the NI PXIe-5622, a 150 MS/s intermediate frequency (IF) digitizer. This combination can be used for spectrum and wideband vector signal measurements over a frequency range from 20Hz to 3.6GHz with analysis bandwidths up to 50MHz. The new VSA features a low phase noise of -129 dBc/Hz at a 10kHz offset at 800MHz, an average noise level of -165 dBm/Hz, a third-order intercept point of +24 dBm and absolute amplitude accuracy of ±0.10 dB.
