David: All: To claim compliance with EN 301489-1 (I am looking at V1.6.1), Clause 8.4.3 Limits, the way the clause is worded, your equipment is not installed in a "telecommunications center" as one would infer from ETSI TR 101 651. The reason for "Table 9: Limits for conducted emissions of equipment intended to be used in telecommunication centres only" is to be in alignment with EN 300 386, which does allow Class A conducted emissions limits, as previously discussed. It appears you will be having to comply with the Section 8.4.3; Table 8, Conducted Limits. William T.

Is Class A conducted emissions ok for a tower-mount VSAT power amp? Depending on the answer, I will either enjoy a beer or have a terrible weekend.

Mike, I owe you a beer now. You just made my day. Unfortunately since we are unlikely to ever been in the same place I'm taking it upon myself to drink it for you too. I'll let you know if you enjoyed it.

Gary, Your recollection is correct, Telecom centres were indeed Class B in Europe. It took us several years in the ETSI EE4 committee to get it changed to class A and even then it was by the somewhat devious means of removing emission limits from EN300 386 and instead referencing directly to EN55022. There are probably a few emc-pstc folk who remember the struggle.

Same question haunts me – I have a vague recollection that for some odd reason European telecommunications centers were Class B but I can’t find the reference. Maybe the distinction is “telecommunication centers ONLY” So I’m also interested in the answer if some one has it.

But, before just assuming that Class A is ok for telecom centers, I'd check with the telecom company to be sure that they don't have a requirement for Class B (I have this gut feel that I've run into that but I can't remember any specifics).

EMC radio equipment standard EN 301 489-1 calls out EN 55022 Class B limits in general, and Class A limits for "...equipment intended for use in telecommunication centres only,..." What is considered a "telecommunication centre?" Unfortunately I can not find any definition for this term in the standard, or in any other standards I have consulted. mc-pstc - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
