Frequency Counter
Feature
* 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
