Embodiment Construction
[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0029] Refer to attached figure 1 , the small signal pulse generation part of the Field Programmable Logic Gate Array (FPGA), the small signal pulse generation process of the present invention is as follows:
[0030] The field programmable logic gate array (FPGA) is controlled by the host computer, namely computer, to output the pulse signal with adjustable delay and pulse width. The computer is connected to the Field Programmable Logic Gate Array (FPGA) through the RS232 serial cable. In order to ensure the reliability of the communication, the baud rate of the serial port is set to 115200, and the parity check is turned on. The serial port program on the computer is written in C# language. The input parameters of the program include the delay...
