ST-NG1 Radio Design Labs Random Noise Generator

The Radio Design Labs ST-NG1 Random Noise Generator is the ideal choice where random white or pink noise is needed. It is suitable either as a reference noise source for audio measurements; or as a masking noise source in engineered sound or counter-intelligence applications, particularly where true random noise is required.

Amplitude limiting circuitry in the ST-NG1 controls extreme peak excursions while preserving random variations of at least 20 dB. The noise generating circuitry in the ST-NG1 is truly random analog noise occupying the full bandwidth from 20 Hz to 20 kHz. This makes the ST-NG1 ideal in masking environments where secure, random noise is required. Unlike the typical digitally-generated pseudo-random noise generators, which can be decoded and removed by effective intelligence equipment, the ST-NG1 produces no repetitive frequency or amplitude pattern.

Four outputs are available on the ST-NG1. Both a mic-level and line-level output are provided from each noise source. A 25-turn gain-trimming potentiometer is provided for the white noise. A separate 25-turn gain-trimming potentiometer is provided to set the pink-noise level, independent of the white-noise setting. The gain trim for each noise source adjusts both the line and mic output for that source. Each output is balanced low-impedance, and may be wired either balanced or unbalanced. All outputs may be used simultaneously.
