[PSES] CB EMC

Dear Members, Under CB scheme, can a CB certificate be issued based an emission test report/standard only? Or, does it require to be supported by both emission and immunity test reports/standards? Thank you very much for your time and I look forward to your comments. Best regards, Grace Lin -

[PSES] Japan PSE Approval

Dear Members, Is EMC compliance a mandatory requirement to obtain Japan PSE approval for a lighting equipment? If yes, does it require emissions only (CISPR 15)? Or. does it require both emissions and immunity compliance? Thank you very much for your time and I look forward to hearing from you.

[PSES] CISPR35

For the good people of the EMC Kingdom, such as the inhabitants of CISPR SC I. Gazing into your crystal balls, any guess on OJ publication and/or national committee harmonization with CISPR35? Will this require a 2d edition for global adoption and whirled peas? Thanks, Brian -

Re: [PSES] crimp hardware for multiple conductors?

In general, and for UL and CSA in particular, crimped terminals are evaluated for the number, size, stranding and types of wire under the crimp. In most cases, only single wires are evaluated, unless the manufacturer specifies that they want additional testing. Wire sizes are critical for any

Fundamentally, a loop is potentially more accurate than a rod, because the use of a rod with the 51.5 dB conversion factor is valid only in the far field, and the (inner) boundary of the far field is not well-defined, especially on real test sites. Below about 10 MHz, the boundary of the far field

Not much different from any other in situ testing I've ever done. Guess I looked like a mad scientist and didn't know it. Thanks, Michael Sundstrom Garmin Compliance Engineer 2-2606 (913) 440-1540 KB5UKT "We call it theory when we know much about something but nothing works, and practice when e

Re: [PSES] CORRECTION (wrong page) Passive Loop Emissions [General Use]

But there was a technical reason for doing so. Not saying right or wrong, because don't have direct experience, but the reason for making loop measurements to an electric field requirement was because there was a prejudice against using a rod antenna, because they felt the loop made more accurate m

Re: [PSES] CORRECTION (wrong page) Passive Loop Emissions [General Use]

Many standards express the limits for magnetic field measurements in dBuV/m, so in E-field. Most also indicate the relation of 51.5 dB to be added to convert H-field into E-field , ignoring close field effects. The 60 cm loop is an old beast, and so are test conventions. Regards, Ing. Gert Gre

[PSES] Passive Loop Emissions [General Use]

Hi All Thanks for all your help. I had a reply from R&S which stated that by changing the units in the Transducer Correction Table to dBuA/m and then entering the Loop Antenna Values (dBS/m) into the table the software will automatically correct the result when the measurement is carried out.

Re: [PSES] CORRECTION (wrong page) Passive Loop Emissions [General Use]

This a different issue. While the field strength outside a simple loop (a model for the EUT) falls off predictably (but not as 1/r initially, as the field from the far side of the loop is not negligible), an EUT may require a much more complicated model, producing a field that falls off either

Re: [PSES] CORRECTION (wrong page) Passive Loop Emissions [General Use]

Precisely. The question is about the magnetic domain only. No need to introduce voltage or 51.5 dB or near/far field. They are all totally irrelevant. With best wishes DESIGN IT IN! OOO - Own Opinions Only www.jmwa.demon.co.uk J M Woodgate and Associates Rayleigh E
