DESCRIPTION DSO203 is based on ARM cortex M3 (STM32F103VCT6) 32 bits platform, providing 72MS/s sampling rate with integrated FPGA and high-speed ADC. Internal 8MB USB disk could be used to store waveform, user application and upgrade firmware. Note: Due to the metal conductive shell of DSO 203, its operating voltage should be controlled under 40V during working in case of any damage to the Quad itself or human DSO Series: Model DSO Nano (DSO211) DSO Note II (DSO202) DSO 212 DSO Quad (DSO203) MCU STM32F103VC STM32F303VC STM32F303VC STM32F103VE ADC MCU internal ADC MCU internal ADC MCU internal ADC AD9288 Channels Analog channel 1 + 1 internal channel 2 analog 2 analog 2 analog, 2 digital Analog Bandwidth 200KHz 1MHz 1MHz 8MHz Max Sample Rate 1MSa/s 10MSa/s 10MSa/s 72MSa/s Maximum Memory Depth 8K 8K 8K 4K Horizontal Sensitivity 1uS/Div~2S/Div(1-2-5sequence step) 1uS/Div~2S/Div(1-2-5sequence step) 1uS/Div~2S/Div(1-2-5sequence step) 0.1uS/Div~1S/Div(1-2-5sequence step) Vertical Sensitivity 20mv/Div~10V/Div(1-2-5sequence step) 20mv/Div~10V/Div(1-2-5sequence step) 20mv/Div~10V/Div(1-2-5sequence step) 50mv/Div~10V/Div(1-2-5sequence step) Input Resistance 1MΩ 1MΩ 1MΩ 1MΩ Coupling DC / AC DC / AC DC / AC DC / AC Auto Adjustment Mode AUTO_FIT AUTO_FIT AUTO_FIT NO Calculation Waveforms -A, RecA, A + RecA -A,-B,A+B,A-B RecA,RecB,RecC -A,-B,A+B,A-B RecA,RecB,RecC -A,-B,A+B,A-B RecA,RecB,RecC Storage 8MB USB flash disk memory 8MB USB flash disk memory 8MB USB flash disk memory 8MB USB flash disk memory APP Installed 1 2 2 4 Operation buttons button,touch area buttons,scrollers buttons,scrollers USB Interface Micro USB Micro USB Micro USB Mini USB Battery 500mAh 500mAh 500mAh 1000mAh Screen Size 2.8inch 2.8inch 2.8inch 3.0inch Screen Resolution 320 × 240 320 × 240 320 × 240 400 × 240 Open Source Application layer Open-Source Quick Starter guide DSO 203 Instruction for beginners SPECIFICATION Analog channel * 2 : [CH_A] [CH_B]; Digital channel * 2 : [CH_C] [CH_D]; Vertical Scale: 20mV-10V/div (1-2-5 step) on x1 probe; 200mV -100V/div (1-2-5 step) on x10 probe Vertical solution: 8 - bit ; Input coupling: AC/DC ; Max input voltage: 80Vpp (x1 probe) / 400Vpp (x10 probe); Storage: 4K per channel Software trigger type: edge, pulse, level (to be added) Hardware trigger type: edge Trigger source: CH1/CH2/EXT Test Signal generator: 10Hz to 1Mhz Storage: internal 8MB USB disk Auto measure: Vmax, Vmin, Vpp, Vavr, Vrms, Freq, Period, Pulse, Duty Cursor measurement: Level, Voltage Display mode: CH1, CH2, EXT, CH1+CH2, CH1-CH2, CH1*CH2 Sampling mode: real time Sampling rate: 1KSa/s - 72MSa/S Power: Li-ion battery Dimension: 98 x 60 x 14.5 mm 3.9 x 2.4 x 0.6 inch Weight: 80g (without battery) WHAT'S IN THE PACKAGE SainSmart DSO203/Quad with battery ×1 X10 Probe Analyzer ×1 X1 Probe Analyzer ×1 Safety Instructions ×1 Hex Key ×1 EAN: 6955170801268 101-10-101 EAN:6955170801275 101-10-102
