What does a frequency counter do?
A frequency counter is a test and measurement instrument that very accurately measures the frequency of repetitive electronic signals, conveying the number of oscillation cycles that occur within a specific period of time. Modern frequency counters also provide a complete statistical analysis and graphical representation of the frequency.
What is a frequency counter used for?
There are a number of applications that require a frequency counter, but they are most often used when measuring radio frequency in electronic and electrical engineering. Frequency counters tend to work best when measuring steady, repetitive signals in environments with low RF noise. Designers and manufacturers of oscillators, clock modules and PLLs make effective use of these instruments.
