White & Pink Noise Generator



The 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.

Wherever white or pink noise signals are needed, the ST-NG1 is the ideal choice. Use the ST-NG1 individually, or combine it with other RDL products as part of a complete audio/video system.
