RDL ST-NG1 White and Pink Noise Generator

Radio Design Labs' ST-NG1 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.

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.
