Korean Spectrum Allocations or Band Plan
Hello Groupies! Is there a location where I may be able to download an English language version of Korea's RF spectrum allocation scheme (sometimes called a band-plan)? This would likely be similar to the USA FCC RR, Part 2. I believe that I may have found the information I need at: http://www.mic.go.kr/eng/jsp/res/res_100_01.jsp which is the Radio Waves Act. Unfortunately, I can only find Hangul versions of this information.

If the camera is in a can, mesh or otherwise, and the can is bonded to the
skin of the chamber, then is doesn't matter whether the control and power
are copper or fiber. In effect, the cables are outside of the chamber.
Special filters and connectors are not needed.
Our dome is mounted in the corner of the chamber, behind the antenna. We
have a clear view of the front of the EUT, and the orientation of the
antenna if we desire with the help of the pan/tilt/zoom capability of our
camera controller.

I use off-the-shelf dome surveillance cameras with an x-y-z+zoom
controller in the chamber at 20 V/m. Smoke covers are available for the
camera mechanism. Contact me off-line for model numbers. We turn the
cameras off during emissions measurements. Our antenna-EUT axis is
somewhat diagonal; we locate the domes toward the side, far off-axis.
Fiber
We send video as Ethernet packets over fiber, but converters are PC-based
and hence large metal objects - not good in an anechoic chamber. Video
over twisted pair may be cleaner than 75-ohm, but what about the
power-supply cable?

You need to be carefull if you are running copper wires out to the
remote display as these will pick up the fields. Hursley EMC Services have
just developed a low cost camera for 10V/m, and we have built a converter
to run the image, pan/tilt and zoom etc out on two fibre optic leads. we
do plan to produce this, but it is unlikely to be ready before mid 2003.

RE: I2C bus sensitivity to EFT
Sir Board level buses, (IIC, etc) are not intended for external use. Note that the electrical part of these standards do not really address EMC issues. These busses are intended as internal constructions (no permanent external port), logic-level, and are mostly just software protocols. I personnaly prefer RS422 or 488 if I need to stream data external to my box. For data port surge suppression issues, look at application notes on the Maxim, TI, or LT websites for serial I/O ICs. good luck Brian -Original Message- From: Alex McNeil [ mailto:alex.mcn...@ingenicofortronic.com] Sent: Thursday, January 16, 2003 12:58 AM To: emc-p...@majordomo.ieee.org Subject: I2C bus sensitivity to EFT Hi Forum, Has anyone on this forum worked with I2C products and maybe be able to advise on the best method to suppress EFT noise that would alow the I2C bus, via external cables, to operate as expected e.g. Good EFT devices? How best to shield the I2C? Other? As always I look forward to your proffesional advice.

You need to be carefull if you are running copper wires out to the remote display as these will pick up the fields. Hursley EMC Services have just developed a low cost camera for 10V/m, and we have built a converter to run the image, pan/tilt and zoom etc out on two fibre optic leads. we do plan to produce this, but it is unlikely to be ready before mid 2003. rgds, Jules Jones From: Ken Javor [mailto:ken.ja...@emccompliance.com] Sent: 15 January 2003 19:29 To: Sandi McEnery; emc-p...@majordomo.ieee.org Subject: Re: Video Cameras for EMC Test Monitoring Just put an off-the-shelf unit from Best Buy or Circuit City in a metal screen box, make sure the screen is very close to the lens, that way it is totally out of focus and only causes a dimming of the picture, not visible distortion.

Pricing for cameras designed to withstand 20V/M is way high do any of you successfully use cameras that are not as sturdy? Or ... does anyone know where we might purchase a used system??

Labelling requirements Part 68
Hello group, TSB168 specifies the labelling requirements for terminal equipment approved by a TCB or an SDoC for connection to a telephone network in accordance with 47 CFR 68. Our OEM (US) mftr tells us this label info (US:AAAEQ##TXXX) can be omitted in certain cases, e.g. when SDoC procedure is followed. We have asked the mftr for evidence, but I would like the professional opinion of this group also.

Video Cameras for EMC Test Monitoring

Can't you just put duct tape over them, if you are not expecting to use them? -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

I2C bus sensitivity to EFT
Hi Forum, Has anyone on this forum worked with I2C products and maybe be able to advise on the best method to suppress EFT noise that would alow the I2C bus, via external cables, to operate as expected e.g. Good EFT devices? How best to shield the I2C? Other? As always I look forward to your proffesional advice. History I have a system that connects 3 products (powered from an in-line external non-earthed power supply, SELV) using the I2C bus via a 1m shielded and 1m shielded curly cable. I use an I2C bi-directional extender IC P82B715 on one of the products. The I2C protocol gets corrupted when I appply the Electrical Fast Transient (EFT) Test per the EMC Standard EN61000-4-4. I have tried shielded cables, several EFT devices and 1nF caps on the lines but with little affect.
