👉 An osculator is a device used to measure and display the frequency of sound waves. It consists of two speakers, usually mounted on a pole or tower, which are connected by a cable. The frequency of the sound waves detected by the oscilloscope is displayed in real-time on the screen. This type of instrument is often used in telecommunications, where it measures the frequency of radio waves and displays the amplitude and phase characteristics of these waves to analyze their properties and performance.
