Tektronix Spectrum Analysers
Spectrum Analysers are instruments used to measure the amplitude of a signal at different frequencies. They are used to measure frequency-related properties of a signal, such as band width, frequency response, group delay, harmonic distortion, noise and distortion, and carrier-to-noise ratio. Spectrum analysers can be used to detect interference, determine the range of frequencies within a given signal, and identify the sources of this interference. They are used in radio frequency engineering, telecommunications, signal processing and broadcast engineering.
