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.
