DSO138示波器故障分析与处理详解
开启/关闭波形参数显示的方法:将光标置于时基位置,长按【OK】键。
保存波形的方法:同时按【SEL】和【+】键。
调出已保存波形的方法:同时按【SEL】和【-】键。
进入测试模式的方法:按住【OK】后按【RESET】键,如果看到LED快速闪动,则说明单片机的PB或PC端口(这些端口包含与LCD连接的连线)存在短路,需要找出后去除;如果看到LED以大约4秒的周期闪动,则可以用电压表查找与单片机端口有关连接线中的可能的开路,具体方法请参阅说明书。
英文资料:
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:
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.
Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers.
Adjustable vertical displacement, and with instructions.
With 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.
With 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.
TFT controller recognition function.
Note:
This DIY kit is not soldered yet!
