High-speed wave acquisition can be used to realize data compression and acquisition. The data after compression is even distributed based on time to keep the waveform and guarantee the peak value. Such a technique has the wave peak value as the main processing object and at the same time show the waveform under limited points restriction. This system uses FPGA (Field Programmable Gate Array), high-speed A/D converter and dual-port RAM as its core units, the sampling rate can be up to 40Msps. Sampling rate and compression ratio could be determined by writing control word to FPGA through microprocessor.
