DIY DSO138 Digital Oscilloscope Kit Electronic Learning Kit
Features: Kits using ARM Cortex-M3 processor (STM32F103C8)£¬ and includes a 2.4-inch color TFT display can be used as ARM test development board. Available source£¬ Capable people can be secondary development on the basis of the suite£¬ for example£¬ it can be changed to Millivoltmeter£¬ data loggers£¬ and so on (we don't supply any technical support about that). Circuit is simple and the kit is inexpensive Characteristics of indicators: - Maximum real-time sampling rate: 1Msps - Accuracy: 12Bit - Sampling buffer depth: 1024 bytes - Analog bandwidth: 0 - 200KHz - Vertical Sensitivity: 10mV / Div - 5V / Div (1-2-5 progressive manner) - Adjustable vertical displacement£¬ and with instructions - Input impedance: 1M - Maximum input voltage: 50Vpp (1: 1 probe)£¬ 400Vpp (10: 1 probe) - Coupling modes: DC / AC / GND - The horizontal time base range: 10s / Div - 50s / Div (1-2-5 progressive manner) - With automatic£¬ regular and one-shot mode£¬ easy to capture the -moment waveform - Available rising or falling edge trigger - Adjustable trigger level position£¬ and with instructions - Observable previous trigger waveform (negative delay) - Can freeze at any time waveform display (HOLD function) - Comes 1Hz /3.3V square wave test signal source
