# Noise Generators A noise signal generator is a type of electronic test equipment that produces a noise, or random signal, to test an electronic product’s frequency response, noise figure, and other important parameters. Pink noise is a random signal that the generator filters to have an equal amount of energy per octave. ValueTronics has traditional noise signal generators and pink noise generators for sale – used and refurbished – for a variety of applications in the engineering, telecommunications, and other industries. ## Products in this collection -
