Description:
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.

Features:
1.This kit uses ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, can be used as ARM test development board.
2.Adjustable vertical displacement, and with instructions.
3.Observable previous trigger waveform (negative delay).
4.Can freeze at any time waveform display (HOLD function).
5.Comes 1Hz /3.3V square wave test signal source.
6.Waveform storage function: will not lose the waveform after power off.
7.Short-circuit and open-circuit detection: can help the user find out the soldering error.
8.TFT controller recognition function.
