German title: Elektromagnetische Verträglichkeit von Multimediageräten und Einrichtungen - Anforderungen an die Störaussendung (CISPR 32:2015 + COR1:2016 + A1:2019); Deutsche Fassung EN 55032:2015 + AC:2016 + A11:2020 + A1:2020
EN 55032, the European harmonized standards adoption of CISPR 32 applies to Multimedia Equipment (MME) and having a rated r.m.s. AC or DC supply voltage not exceeding 600 V and intended primarily for professional use, including equipment that falls within the scope of CISPR 22 and CISPR 13. Procedures are given for the laboratory measurement (on site testing excluded) of the levels of spurious signals generated by the MME and limits are specified within the standard for protection of radio services in industrial, commercial or residential environments.
The international standard EN 55032 divides equipment, devices and apparatus in two classes, depending on the type of end using environment:
Class A equipment that may not offer adequate protection to broadcast services within a residential environment.
Class B equipment that offers adequate protection to broadcast services in residential environment.
Equipment intended primarily for use in a residential environment shall meet the Class B limits. All other equipment shall comply with the Class A limits.
Examples of Multimedia equipment (MME):
information technology equipment– equipment having a primary function of entry, storage, display, retrieval, transmission, processing, switching, or control of data and/or telecommunication messages and which may be equipped with one or more ports typically for information transfer. (Office machines, electronic business equipment and telecommunication equipment.)
Conducted emission requirements for AC/DC mains ports, telecommunication ports, signal ports must be satisfied in frequency range 150kHz-30MHz.
Radiated emission requirements must be satisfied in frequency range:
30MHz-1GHz | if internal frequency is up to 108MHz |
30MHz-2GHz | if internal frequency is up to 500MHz |
30MHz-5GHz | if internal frequency is up to 1GHz |
30MHz-6GHz | if internal frequency is higher than 1GHz |
Internal frequency – highest fundamental frequency generated or used within the EUT or highest frequency at which it operates. This also includes frequencies which are solely used within an integrated circuit.
All measurements below were successfully completed for MME Class A. Radiated emissions were measured in the frequency range of 30MHz-6GHz.
