The measurement precision based on that the tradition examines the cymometer of the principle frequently will be reduced with the decline of signal frequency be examined, until greater limitation when having in being the practical,and,etc. precision cymometer not only measurement precisions higher, and can keep the invariable test precision in the area of whole frequency. The signal anti-interference ability of frequency is strong, easy to transmit, can obtain higher measurement precision, so is examining the research of the frequency method and is being paid attention to. It is a precision cymometer based on AT89S51 one-chip computer to originally design. Input signal for peak peak value sine signal of 5v, frequency measure range 10HZ input 100MHZ, frequency measure precision 0.1%. Adopt 1602 liquid crystal displays and reveal the result of measuring.

Based on the traditional principle of measuring the frequency of the frequency of measurement accuracy will be tested with the frequency and reduce the decline in the more practical limitations, such as accuracy and frequency of not only has high accuracy, but in the frequency region To maintain a constant test accuracy. - Frequency signals strong anti-interference capabilities, easy to transport, receive higher accuracy, frequency of measurement method of increasing attention. The design is based on AT89S51 SCM, and other precision frequency. Input signal for the peak of the peak 5 v sine signal, the frequency range 10 HZ ~ 100MHZ, frequency measurement accuracy of 0.1 percent. By 1602 LCD display results.
