Preface

• This example selects VN1630 Hardware as a test , Through the one behind the box I/O Analog input of port PIN Feet to complete the test

• Whether it's using the reading method of the power supply itself , It's better to watch the waveform of the power supply voltage drop with an oscilloscope , Can't do time synchronization , accurate , So choose VN1630 Of I/O Analog input of port &
