Noise suppression sheet for digital devices and equipment - Characterization of parameters of noise suppression sheet Ingestion-build-83346 What is this BS 6840-131 Scope suppression sheet (NSS) for digital devices and equipment used in a frequency range between 30 MHz to 30 GHz. Guidance is given for uniform presentation of the properties of noise suppression sheet, intended for use in manufacturers and users technical data. NSS suppresses noise at its source, rather than absorbing noise at a distance. Therefore NSS is distinguished from RF wave absorbers used in free space. This standard addresses the
