Simple Timing Signal Analysis Device-XY Mode Displays the Multichannel Shift Waveform

Abstract

We designed and implemented a simple timing signal analysis device, which displayed multichannel shift waveform without overlapping from left to right on the Oscilloscope screen using X-Y mode as signal input. In order to meet the requirements of high speed sampling rate, we took microcontroller STM32F407VGT6 to collect, storage, analysis signal, and calculate the result wave though high speed DA conversion module to display on the Oscilloscope screen. we took microcontroller STM32F103RB to realize the shift clock circuit and 8-channel digital signal, and adopt the dial-code switch presents the 8-bit trigger word TW. after several test, the signal analysis device could realize the trigger time position adjust at all, time marker line be shifted manually, LED light displayed the status word corresponding to the flag line, and playback two shift cycle timing waveform and other functions simply and efficient. through numerical simulation and experimental analysis, we found that this simple device can greatly display multichannel shift waveform easily and precisely.
