In order that the paper was solved high-precision frequency measurement on the computer measurement system, there was proposed a method which one of the multi-channel and equal-precision frequency measurement based on the FPGA (Field Programmable Gate Array). Design of the frequency-measurement system. Frequency measurement resolution is achieved 1 Hz at 5 kHz-500 kHz.
