ARM DSO203 4 Channel Mini Nano V2 Quad Pocket Digital Oscillo​scope

 Overview

Fulfilling the basic engineering requirements, DSO 203 is a pocket-sized 4 channel digital storage oscilloscope for common electronic engineering tasks.

 

 

DSO 203 is based on ARM cortex M3 (STM32VCT6), providing 72 MHz analog bandwidth with integrated FPGA and high speed ADC, equipped with400*240 TFT LCD widescreen USB connection and rechargeable battery. Convenient to carry as it weights only 80g without battery.

 

Features

1.    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.

2.   MCU and the FPGA are selected QFP100 package, ADC selected QFP48 package.

3.   36M+36Msampling frequency, the use of the ADC AD9288-40 chip, single-channel maximum sampling frequency of the 72M.

4.   FIFO RAM has a maximum operating frequency of use of> 200MHz low-power FPGA to achieve.

5.  The AD9288-40 Overclocking to achieve 72M+72M sampling frequency, so that the maximum single-channel sampling rate up to 144M.

6.   Analog channel circuit using unity gain> 150MHz op amp, so the actual 30MHz analog bandwidth is expected to do more.

7.   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.
