Agilent/Keysight M9203A

The Keysight M9203A is a PXIe high-speed digitizer and wideband digital receiver engineered for wireless communication, radar, and satellite signal acquisition. This dual-channel, 12-bit instrument captures signals across DC to 2 GHz at sampling rates up to 3.2 GS/s, delivering 64 dBc dynamic range and ±200 fs channel-to-channel skew stability. The module integrates a Xilinx Virtex-6 FPGA for real-time signal processing and custom algorithm deployment, with optional digital down-conversion on phase-coherent channels. Data throughput is sustained via PCIe Gen2 (x8) backplane, enabling continuous streaming to disk storage. Configurable 1 V or 2 V full-scale input ranges accommodate diverse signal levels, while 15 ps RMS trigger time interpolator precision ensures deterministic timing.
