ITE Emissions above 1 GHz

I have an Information Technology device that intentionally generates and uses 2.45 GHz signals. EN55022 does not provide limits above 1 GHz. Is there another harmonized EN that can be applied for spurious emissions above 1 GHz? If not, will this product have to be submitted to a Competent Body?

EPA Hazardous Materials Lithium Batteries disposal

Group, I've got two general questions regarding hazardous material: 1). Any experience with identifying materials defined as hazardous by the EPA? (Is there a list somewhere??) My customer is interested in steps that should be taken to: * Avoid exposure * Avoid injury * Proper disposal

RE: Which Antenna?

Allen, We have used a biconilog for radiated emissions testing in our 3m semi-anechoic chamber for the past three years. We have done extensive correlation studies to the biconicals we own and found there to be little issue with using the biconilog. Its well balanced and therefore, we're not

RE: Which Antenna?

All, I didn't get out a tape measure, but I believe a bilog antenna is taller than a bicon antenna in the vertical polarity, and would be closer to the floor at the minimum antenna height of 1 m (for most test procedures.) For that reason, I believe there would be more coupling to the ground

RE: Which Antenna?

Thanks for your response. Since our lab will be used for pre-compliance in an RD facility, I foresee several engineers wanting to use the equipment. I would hate to see someone drop an antenna or knock one off the wall that isn't being used. I didn't think of the scenario you mentioned where an

RE(2): Which Antenna?

Allen, I would like to clarify one point. I use a biconilog in the chamber. All chamber work is rough or ballpark. I use a biconical and a log periodic on the OATS. There are a few articles around that identify repeatability issues with a biconilog. However, for pre-compliance biconilog

RE: FW: Compliance of a USB telephone

Gary, My firm makes video-phone related products. Each has a basic rate ISDN interface. Traditionally, for the EEC we have tested to ETSI specs TBR3 (network signalling) and TBR8 (audio). Since April this year, we have been able to use existing approvals and self declare for the new kit, but we

Re: Which Antenna?

Mr. Allen, I have had some experience with biconilog, log periodic, and biconical antennas for both emissions and immunity testing. I never had any issues with the biconilog when used for immunity testing. However, after using the biconilog for emissions testing on a 3 meter OATS, I went back

RE: Which Antenna?

Allen, We have a similar chamber with similar issues. We use the immunity chamber as a precompliance emissions chamber also. It's a lot of work to remove the tiles from the floor so we left them in place for precompliance emissions investigations. We use a biconilog antenna for both emissions

RE: Which Antenna?

For emissions testing, the antenna should have a well balanced design when used over a ground plane. Perhaps the antenna you are considering is not well balanced. The balance issue shows up in the vertical orientation when there is coupling to the ground plane and is not unusual in some bicons. I

RTTE Statement Translations?

Hello Group, Does any of you know of a web location where I might get the 11 language translations of the proposed manual statement (Hereby, [Name of manufacturer], declares that this [type of equipment] is in compliance with the essential requirements and other relevant provisions of Directive

RE: FW: Compliance of a USB telephone

Morning Geoff, The copper interface has been my only point, and the USB phone doesn't have it. I agree and said, in an apparently round-about method, the part that really is phone-like has to operate like a phone, including billing, acoustic, tear-down and set-up as you mention below. No

Which Antenna?

Greetings, I am having a fully anechoic pre-compliance test chamber built. By fully anechoic, I mean ferrite tiles will be installed on the floor as well as the walls and ceiling. The inner dimensions of the chamber will be 24 feet long by 14 feet wide by 13 feet high. The chamber will be

New Edition of EN 61010-1

Dear List, I've received word of an Edition 2 for IEC 61010-1 which was recently approved in a vote within the IEC. Does anyone have any information on when or if this will be published by the EC (a DOP), or when an ultimate DOW might be set? Many thanks, Paul O'Shaughnessy Affymetrix,

prEN 61312-1

To any that might know, I have just heard that CENELEC has launched a formal vote on prEN 61312-1, Protection Against Lightning Electromagnetic Impulse: General Principles. Does anyone have a copy of this document that you can share? Please advise. Best regards, Ron Pickard

Standards for a Position Indicator

Hi, I am currently researching the appropriate standards (UL, CSA, IEC) for a position indicator. The indicator is mounted on a valve. It indicates whether the valve is open or closed. It is a 10 to 30 Vdc, 150 mA, PNP device. The valve is used in the pharmaceutical industry and controls the

RE: Japanese regulations in 2.4 GHz ISM band?

Shah, The regulating or testing agency is Telec(see link below). I don't know what the name of the standard is, but I know you can buy it from Telec. To my knowledge, it is only printed in Japanese. I am not sure if they offer an electronic copy or not. Although not required, it sure makes

RE: FW: Compliance of a USB telephone

Gary, Your comment is a valid one at the copper interface. However, the telephone call set-up, content and tear-down have also to be considered. There is a trend with PC modem cards, to transfer most of intelligence back to the host CPU. There is now software that will permit the PC user, via a
