Universal Frequency Counter
SS7200/7300/7400
SS7400 Universal Frequency Counter/Timer/Analyzer introduces high reliability and large scale integrated circuit.
Brief Introduction
Universal Frequency CounterSS7400 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
Minimum measuring resolution 11 digits/s
Time resolution 50ps
Maximum frequency’s measurement can reach to 16GHz (options)
Measures Frequency, Period, Duty Cycle, Frequency Ratio, Totalize, Phase Difference, Pulse Width, Time Interval and DCV.
Utility statistics functions of multi-average, maximum, minimum, PPM, standard deviation and Allan Variance for frequency measurement
Stores 15 group status
High-stability crystal oscillator is optional
