This DSO138 Digital Oscilloscope Kit adopts ARM Cortex-M3 processor and with 2.4 inch TFT screen. It's easy and reliable for circuit operation. It can display frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.
ARM Cortex-M3 Processor (STM32F103C8)
2.4 inch color TFT display screen included, the kit can be used as ARM test development board. And can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers.
Automatic, Regular and One-shot Modes
Easy to capture the moment waveform. Available rising or falling edge trigger, observable previous trigger waveform (negative delay). Can freeze at any time waveform display (HOLD function). Comes 1Hz /3.3V square wave test signal source.
Waveform Parameter Digital Display
Including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.
Waveform Storage Function
Will not lose the waveform after power off.
Short-circuit and Open-circuit Detection
Can help the user find out the soldering error.
Other Functions
TFT controller recognition function.
