Feature: 3" 240 × 400 widescreen color TFT LCD screen, STM32 is the master MCU, with the FPGA to implement the control and management of external ADC and data cache. MCU and the FPGA are selected QFP100 package, ADC selected QFP48 package. Two 72MSa/s analog channels and two digital channels. 36MSa/s+36MSa/s sampling frequency, the use of the ADC AD9288-40 chip, single-channel maximum sampling frequency of the 72MSa/s. FIFO RAM has a maximum operating frequency of use of> 200MHz low-power FPGA to achieve. The AD9288-40 Overclocking to achieve 72MSa/s+72MSa/s sampling frequency, so that the maximum sampling rate up to 144MSa/s. DSO203 sampling depth of the current situation for the multi-channel 4096 points per channel, single-channel work cases, 8192 points.
