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.
Mounting the ST-NG1 in an STS-RF1 shielded chassis is recommended in installations where excessive rf interference levels are anticipated from sources such as WIFI transmitters.

Installation of these products by the Purchaser shall constitute Purchaser’s acknowledgement and acceptance of the terms and
conditions for sale and of this warranty, and shall constitute the Purchaser’s determination of the suitability of this product for the
Purchaser’s intended application. Radio Design Labs, Inc., also referred to as RDL®, warrants to the Purchaser that products
manufactured by RDL are free from defects in material and workmanship. This warranty applies to the period of three years from the date
of shipment, except for component parts or products purchased from other sources and supplied by RDL. Such component parts or
products bear only the warranty of the manufacturer thereof in effect at the time of shipment to the Purchaser. RDL will, without charge,
and after written notice has been received and acknowledged by RDL, repair an RDL product if proved to be defective according to the
usage of the trade, when such equipment is received by RDL at the location it designates with shipment costs prepaid by the Purchaser.
RDL shall not be liable for any expense whether for repairs, replacements, material, service, or otherwise, incurred by the Purchaser or
modifications made by the Purchaser to the product. No equipment shall be deemed defective if it shall fail to operate in a normal or
proper manner due to exposure to excessive moisture in the atmosphere, excessive temperature extremes, improper environmental
cleanliness, or any other environment not consistent with the principles of good engineering practice. In no event shall RDL have any
liability for consequential damage or expense directly or indirectly arising from the use of the products, or any inability to use it either
separately or in combination with other equipment or materials, or from any other cause, whether used in accordance with instructions or
not. This warranty is void if equipment is altered in any way by other than RDL. RDL products are NOT intended for use in life support
appliances, devices, or systems. Use of RDL products in such applications is done solely at the liability of the reseller/installer and/or end
user. RDL reserves the right to change design parameters and specifications at any time without notice. The performance measurements
