A high-speed signal recorder is designed to meet the requirement of high-speed signal real-time acquisition and storage. The recorder samples signal by the high performance ADC,and stores the real-time data in the FLASHs array. To improve the data storage rate, the parallel bus, interleave two-plane page program and multi-stage pipeline technologies are applied. The recorder’s sampling rate can reach 8bit, 200MSPS, and the real-time sampled data can be stored at a rate of 200MB/s.
