This system based on C8051F020 to achieve equal precision frequency measurement using the SCM flexible speed control function and
Advantage dramatically improves performance and measurement accuracy. Previous frequency measurement is counted directly at high frequencies and low frequencies of indirect measuring week
Method of measurement accuracy tends to be affected with the change of the measured frequency. In order to overcome the high and low band frequency measurement accuracy of measurement
Defects of varying degrees, dual counter designed to achieve equal precision frequency measurement. Precision measurement method not only has a high
Measurement accuracy, but also in the entire region remains constant over frequency measurement accuracy.
