Abstract

Frequency meter logical resource occupancy is the research object of electronic information field. To solve the precision of the frequency meter and reduce the occupation of logical resources, this paper designs a measurement system based on FPGA, which can switch between high frequency and intermediate frequency modes freely. Firstly, the signal generated by the dual-channel DDS function signal generator is input into the conditioning circuit for corresponding processing, and then the high-frequency mode or mid-frequency mode is selected by the DIP switch and input to the FPGA chip for counting. Finally, the measurement results are displayed on the LCD. The digital frequency meter can execute the corresponding functional test according to the mode selected in advance after testing, and it is found that compared with the modeless high-precision frequency meter, the high frequency has less 103 logical resource occupations in the high-frequency mode, and the mid-frequency has less 242 logic resources in themed-frequency mode.
