EN 55032: 2012 Electromagnetic compatibility of multimedia equipment – Emission requirements (CISPR 32: 2012)

Scope

EN55032:2015 applies to multimedia equipment (MME) having a rated r.m.s. AC or DC supply voltage not exceeding 600V. Equipment within the scope of the following standards is within the scope of BS EN55032:2015 – EN55013, EN55022, CISPR 13 and CISPR 22. MME is intended primarily for professional use. BS EN55032:2015 does not require “in-situ” testing, this is outside of the scope.

Classifications

BS EN55032 splits equipment and devices into two classes, this all depends on the intended environment for the equipment.

Class B – Equipment that offers adequate protection to broadcast services in residential environments.

Class A – Equipment that mat not off adequate protection to broadcast services within residential environment.

So equipment intended for residential environments shall meet the Class B requirements. All other environments shall meet the Class A limits for both conducted and radiated emissions.

All equipment passing Class A should have the following placed in the manual:

Warning: This equipment is complaint with Class A of CISPR 32. In a residential environment this equipment may cause radio interference.

Examples of Multimedia Equipment

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.

• audio equip­ment– equip­ment which has a pri­mary func­tion of gen­er­a­tion, input, stor­age, play, retrieval, trans­mis­sion, recep­tion, ampli­fi­ca­tion, pro­cess­ing, switch­ing or con­trol of audio sig­nals. (CD play­ers, receivers, audio ampli­fiers, mix­ers.)

• video equip­ment– equip­ment which has a pri­mary func­tion of gen­er­a­tion, input, stor­age, dis­play, play, retrieval, trans­mis­sion, recep­tion, ampli­fi­ca­tion, pro­cess­ing, switch­ing, or con­trol of video sig­nals. (Video play­ers, cam­eras, TV stu­dio equip­ment.)

• broad­cast receiver equip­ment– equip­ment con­tain­ing a tuner that is intended for the recep­tion of broad­cast ser­vices. (Tele­vi­sion and radio ser­vice receivers, ter­res­trial broad­cast receivers.)

• satel­lite broad­cast and/​or cable trans­mis­sion equip­ment

• enter­tain­ment light­ing con­trol equip­ment– equip­ment gen­er­at­ing or pro­cess­ing elec­tri­cal sig­nals for con­trol­ling the inten­sity, color, nature or direc­tion of the light from a lumi­naire, where the inten­tion is to cre­ate artis­tic effects in the­atri­cal, tele­vi­sual or musi­cal pro­duc­tions and visual pre­sen­ta­tions

• or com­bi­na­tions of upper men­tioned equip­ment

Require­ments
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 rage:
30MHz-​1GHz if inter­nal oscil­la­tor fre­quency is up to 108MHz
30MHz-​2GHz if inter­nal oscil­la­tor fre­quency is up to 500MHz
30MHz-​5GHz if inter­nal oscil­la­tor fre­quency is up to 1GHz
30MHz-​6GHz if inter­nal oscil­la­tor fre­quency is higher than 1GHz

Inter­nal oscil­la­tor 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.
