ARM DSO203 Pocket DS203 Oscilloscope Cortex M3 CPU 8M Hz
Model Number:ARM DSO203
2* Analog channel ::[CH_A] [CH_B]
2*Digital channel::[CH_C] [CH_D]
CPU:ARM Cortex M3
DSO203/Quad is a pocket size 4 channel digital oscilloscope for common electronic engineering tasks. It's based on ARM cortex M3 (STM32VCT6), providing 72Mhz analog bandwidth with integrated FPGA and high speed ADC. Internal 2MB USB disk could be used to store waveform, user application and upgrade firmware.
*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.
*At the same time to reduce the size and easy to DIY manual welding, MCU and the FPGA are selected QFP100 package, ADC selected QFP48 package.
*36M 36M sampling frequency, the use of the ADC AD9288-40 chip, single-channel maximum sampling frequency of the 72M.
*FIFO RAM has a maximum operating frequency of use of> 200MHz low-power FPGA to achieve.
*The AD9288-40 Overclocking to achieve 72M 72M sampling frequency, so that the maximum single-channel sampling rate up to 144M.
*Analog channel circuit using unity gain> 150MHz op amp, so the actual 30MHz analog bandwidth is expected to do more
*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.
