MX53131A Frequency Counter

MX53131A high-precision universal counter is a high-precision frequency and time measuring instrument newly developed by Maxwellon. They are based on high-performance AVR microcontrollers for functional control, measurement timing control, data processing, and result display. Using reciprocal counting technology and digital interpolation technology to achieve high-precision measurement across the entire range. In addition to measurement functions such as frequency, period, time interval, pulse width, duty cycle, phase, count, etc., there are also measurement and operation functions for multiple averages, maximum values, minimum values, standard deviation, Allen variance, maximum deviation (maximum minus minimum value), single deviation (minus preset value), and PPM.
