Overview

Frequency counters are electronic instruments used to measure the frequency of an incoming signal. They are essential in various fields, including telecommunications, electronics, and laboratory research, for accurately determining the frequency of signals in hertz (Hz). These devices are valuable for troubleshooting and ensuring the proper operation of RF systems, oscillators, and signal generators.

FAQ
