Description

A measuring instrument used to determine the frequency of an electrical signal, typically in the RF or microwave range. It works by analyzing the periodic oscillations of the signal and displaying the frequency (in Hz) on a digital or analog readout. Frequency meters are essential tools in RF and communication systems for calibrating equipment, monitoring signal stability, and ensuring accurate frequency operation in systems such as transmitters, oscillators, and signal generators. They are often used in lab testing, fieldwork, and system diagnostics.
