SS7402 Universal Frequency Counter/Timer/Analyzer introduces high reliability and large scale integrated circuit and CPLD, the 16-bit Microchip microcontroller is used for functions control, measurement timing control, data processing and results display. 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. Machine clock frequency is 10MHz. Not only the internal gate can realize the automatic measurement, but also the external signal trigger can control measurement. Instrument can automatically detect and convert the external frequency standard 5MHz or 10MHz. 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.
