NATIONAL Instruments has introduced the NI PXIe-5665, a 3.6GHz RF vector signal analyser with leading phase noise, average noise level, amplitude accuracy and dynamic range.
The vector signal analyser’s PXI platform facilitates peer-to-peer streaming, and includes a flexible multiple input, multiple output (MIMO) architecture for phase-coherent measurements.
According to National Instruments, the NI PXIe-5665 VSA offers measurement speeds that are at least five times faster than traditional rack-and-stack instruments, ideal for demanding automated RF test applications.
The RF analyser is said to be affordable, while combining 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 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) digitiser.
The solution is suited for spectrum and wideband vector signal measurements over a frequency range from 20Hz to 3.6GHz with analysis bandwidths up to 50MHz. The 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.
