Pink & White Noise Generator

IE20B

The IE-20B is a truly portable, state-of-the-art noise generator, designed to handle the most exacting laboratory or field requirements. Unlike gas-discharge tube and noise diode methods, the digital techniques used in the IE-20B allow the generation of noise signals that are statistically well-defined and very stable.
