S43180 Series Frequency Counter

S43180 series high-precision frequency counter is a high-precision frequency measurement instrument. It has a frequency measurement resolution of 10 bits per second. The whole machine scheme adopts countdown technology and digital interpolation technology to realize the high-precision measurement of the instrument. It has measurement functions such as frequency, period, frequency ratio and powerful mathematical statistics operations (maximum value, minimum value, average value, PPM, standard deviation, Allan variance).

S43180 series has reliable performance, complete functions, high measurement accuracy, wide frequency measurement range, high sensitivity, large dynamic range, high cost performance and easy to use. It is especially suitable for frequency measurement in scientific research and measurement fields such as aerospace, crystal oscillators, and components.
