Description
The HPx-310 Radar Signal Output Card is a high-performance radar signal output card designed by Cambridge Pixel to generate analogue radar video from digital sources. It allows seamless integration of processed radar data back into legacy radar displays, simulators, or networked radar systems. With precise timing and low-latency performance, the HPx‑310 can output radar video, trigger, and azimuth signals with high fidelity, supporting both single and dual-channel configurations.
Its FPGA-based design enables real-time generation of radar returns with configurable pulse lengths, amplitudes, and scan patterns. The card supports multiple output modes, including 50 Ω or 75 Ω terminated analogue video and standard azimuth formats. It is compatible with a wide variety of radar simulators, SPx software suites, and operational radar systems, making it ideal for testing, training, and system integration.
