Gigabit Streamer is a high-performance, bidirectional data-streaming instrument that expands the capabilities of the Moku platform into advanced data acquisition, logging, playback, and signal emulation. It enables fast, continuous streaming of raw data directly to storage systems or between multiple Moku devices, making it ideal for wideband signal monitoring and long-duration testing. With streaming speeds up to 80 Gbps via 100 GbE or up to 5 Gbps using dual 10 GbE interfaces, Gigabit Streamer supports real-time capture and replay of complex signals, including RF and high-speed sensor data. Its FPGA-based architecture allows custom real-time processing before streaming, enabling efficient workflows for HIL testing, RF emulation, automation, and AI/ML data collection.
