PXI RF Vector Signal Analyzer Is Asserted to Outperform Rack-and-Stack Instrumentation

PXI RF vector signal analyzerNational Instruments introduced the NI PXIe-5665, a 3.6 GHz RF vector signal analyzer (VSA) that delivers desirable RF performance in a PXI form factor. The company asserts the VSA features 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 multiple input, multiple output (MIMO) architecture for phase-coherent measurements; and offers measurement speeds that are said to be at least five times faster than traditional rack-and-stack instruments – all of which make it ideal for demanding automated RF test applications. 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 creates desirable solution for spectrum and wideband vector signal measurements over a frequency range from 20 Hz to 3.6 GHz with analysis bandwidths up to 50 MHz. The new VSA features 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.
