| Abstract: | The testing system for measuring communication cable breakpoint based on TDR (time domain reflection) is introduced. The system uses AT89C52-MCU as a control core,and FPGA (Field-Programmable Gate Array) as test main body to transmit and receive pulse,and collects the trip time of pulse in communication cable,so that the system realizes the communication cable breakpoint measurement. The system is in simple construction and easy operation.It offers precise distance measurement and excellent effects. |
