This standard provides performance requirements and methods for testing the performance of analogue, sampled-data, and digital implementions of band-pass filters that comprise a filter set or spectrum analyser. The extent of the passband region of a filter's relative attenuation characteristic is a constant percentage of the midband frequency for all filters of a given bandwidth. The Amendment A1 concerns EMC, i.e. specifications regarding the immunity of the apparatus and regarding the upper limits on radio-frequency emissions.#,,#
