The problem to design a digital storage oscilloscope, to Xilinx, 200,000 FPGA chip as the core, supplemented by the necessary peripherals (including signal conditioning, sample and hold, internal trigger, A/D converter, D/A conversion and I/O modules) the use of VHDL language programming, arbitrary waveform one-shot, continuous playback is triggered, and storage, in accordance with the requirements of the vertical sensitivity and sweep speed of the gear set. Signal acquisition, it will be the external input signal conditioning by the signal conditioning modules to the A/D circuit input range, after A/D converted into the FPGA s internal dual-port RAM for high-speed cache, and the results through the D/A converter to give general oscilloscope shows completed, the low-frequency signals in real-time sampling and high-frequency signals equivalent sampling and data storage playback. Been tested, the system as a whole indices are good, the vertical sensitivity and scan speed indicators meet
