ZYNQ version of high-performance open source oscilloscope: 1Gsps sampling rate, 100MHz bandwidth, capture rate 22000 wfm/s, Raspberry Pi for waveform rendering

 
Overview

The biggest feature of this open source oscilloscope is its strong waveform rendering (afterglow/fluorescence) effect. At the beginning, the author used Raspberry Pi Module 3, which can render 22,000 frames per second. In the later stage, NVIDIA Jetson is used, which can render 130,000 frames. frame.

ZYNQ's FPGA is responsible for triggering and data acquisition, and A9 is responsible for transmitting data to the Raspberry Pi. Then the Raspberry Pi does the display processing. The ADC uses 1Gsps HMCAD1511.
