ABSTRACT

In this paper, the synchronous time interval measurement system of multichannel timing generator based on FPGA is introduced. FPGA is used to measure the time interval of 42 high-precision timing signals, and TCP/IP interface is used to display between the machine and computer. Hardware design of time interval measurement system and the selection of measurement mode of upper computer are emphasized. The design can ensure that the timing measurement error of each channel is less than 1us, which has multiple timing measurement methods. The system has the advantages of high precision, simple operation and good applicability, which has been successfully applied to the front line of timing measurement in military shooting range.
