2.7 GHz PXI Vector Signal Analyzer—The PXI‑5661 features wide real-time bandwidth, optimized for automated test in a compact, 3U PXI package. It is ideal for high-throughput RF acquisition and measurements. The 20 MHz wide onboard quadrature digital downconverter (DDC) significantly reduces the required load size and the time needed to transfer waveform data to the host controller or PC. This functionality works well for engineers who need data streaming with rapid response times for software defined radio (SDR), real-time signal processing, or faster transfer times for spectral monitoring applications.
