Frequency Counter


* High accuracy with minimum measuring resolution

10 digits/s

* 16-bit microcontroller is used and the speed of data

processing is fast.

* Maximum frequency’s measurement can reach to

26.5GHz (options)

* Utility statistics functions of multi-average, maximum,

minimum, PPM, standard deviation and Allan Variance

for frequency measurement

* High-stability crystal oscillator is optional
