A good friend is leaving

For those of you who deal with the FCC, I was sorry to hear that Ed Gibbons, possibly the most helpful government employee to have ever existed, is retiring in a couple of weeks. I will miss his commitment to excellence in service. -- Brent DeWitt U.S. EMC Technical

We manufacture application specific subassemblies (keyboards) that are used on special computer systems, workstations etc. We typically do not place these goods on the market, as they are designed specifically for a particular system, and have no intrinsic functions of their own. Sometimes

Distance of Measurements

For measuring emissions per CISPR 22B what is the proper distance for the placement of the antenna? Is it 3m? or 10m? [I'm running across reputable labs that claim there is nothing wrong with measuring everything at 3m, just like FCC B.] - Robert -

Re: Re[2]: EMC REGULATIONS IN TAIWAN

Hi! All, Thanks for the info. on EMC regulations in Taiwan. What about Product Safety Regulations in Taiwan? Is there any mandatory requirement especially on mains (AC) operated ITE equipments? Any special labelling needed? If yes, does Taiwan recognise equipments that are already UL, CSA and

RE: Distance of Measurements

Robert, Reference and therefore preferred test distance for measurements to CISPR 22 is 10 meters for both classes A and B. Measurements at closer distances, including 3 meters are acceptable. In a case of dispute results from 10 meters will take precedence. Mirko Matejic Coauthor of CISPR 22,

Re: Distance of Measurements

CISPR22 measurement distance is 10m. Section 11.2.1 of the standard does allow for a test distance of less than 10m under certain conditions (e.g. high ambient noise levels). Any measurements made at a distance other than 10m should be corrected by 20log(10/d) (where d is the measurement

Hi Martin. You wrote about LVD and PLC's. Don't lose sight of the fact that the LVD states that the equipment as described should be safe. EN61010 (measurement and control equipment, which may loosely describe PLC's) requires that the equipment should be safe in all interpretations of the
