  • 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.
  • As low power, low-cost, QFP package and other conditions of the FPGA, storage capacity is not large, so DSO203 sampling depth of the current situation for the multi-channel 4096 points per channel, single-channel work cases, 8192 points.
  • Bandwidth: 8MHz
