Brief Introduction
SS7402 Universal Frequency Counter/Timer/Analyzer introduces high reliability and large scale integrated circuit. With multi-cycle synchronous, reciprocal count and TDC technology combined, the measurement accuracy is improved. It has the measurement function of frequency, period, time interval, pulse width, duty cycle, count, phase difference, also with the measurement computing function such as multiple average, maximum, minimum, standard deviation, Allan Variance, a single relative deviation. The instrument has advantages of stable performance, complete functional, wide measuring range, high sensitivity and precision, small size, nice outlook, easy to use and reliable.
Features
