NATIONAL Instruments has announced NI PXIe-5665, a 3.6GHz RF vector signal analyser (VSA).
The VSA is said to deliver best-in-class RF performance in a PXI form factor, with industry-leading phase noise, average noise level, amplitude accuracy and dynamic range.
The VSA’s PXI platform also facilitates peer-to-peer streaming; includes a flexible MIMO architecture for phase-coherent measurements; and offers measurement speeds that are at least five times faster than traditional rack-and-stack instruments.
The analyser combines high-end performance with modular flexibility into one compact package, so engineers can use the same instrument from design to production.
The VSA combines the NI PXIe-5603 downconverter with the NI PXIe-5653 local oscillator synthesiser and the NI PXIe-5622, a 150 MS/s intermediate frequency (IF) digitiser.
This combination is said to be ideal 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 10 kHz offset at 800 MHz, an average noise level of -165 dBm/Hz, a third-order intercept point of +24 dBm and absolute amplitude accuracy of ±0.10 dB.
Engineers can mix and match the VSA with a variety of modules and control an entire automated test system with NI LabVIEW graphical system design software.
