please accept my Apology
EMC Forum, I apologize for the "Shameless Advertisement on the Technocal Forum. It was not my intention to break any rules of the IEEE society. I have been a member for quite some time and thought that I have seen similar FREE OPEN HOUSE events in the past. I have learned much from this group and believe that I have contributed positively as well. After reviewing some past e mails, I realized that these aforementioned events were in response to requests from members of the group. After reviewing the rules, I have realized that this is contrary to the EMC-PSTC rules. Please accept my apology! I hope to remain a member of the forum. Regretfully Yours, Bill ps. For those of you, out there, who know me, Please don't abuse me too much. I'll take what I deserve like a man! --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

RE: Field wiring terminal size
Peter, Thanks for the response. Our original design called for separate circuits, but for a variety of reasons, we decided to go with the single 100 A input.

RE: Agilent EMC analyzer
I have one, I LOVE it! For the price (I paid around $16k), you can't go wrong! Color Display 3-Traces Built-in Pre-Amp AM/FM Demodulation Hard Disc 3.5 Floppy Disk Limit set-up (packaged floppy has limits for all popular int'l emissions standards) Correction factors for popular antennas (also included) Create data lists (can compare peak, avg. quais-peak) and there's plenty more. You get the picture . . . the rest is on the brochures. It is easy to set-up and use. It's portable - I've taken it to the lab when I encountered unforeseen problems, took data with my set-up, and saved it onto the floppy as an aid for troublshooting. You can also by the report generation S/W package and create some really nice reports. The analyzer can be standalone or PC controlled. For continued emissions compliance it's nice too. If you're changing vendors for a device (IC, oscillator, etc), or considering an ECO on a printed circuit, you can do a 'before & after' to make sure that you haven't affected the emissions compliance. I save the 'before & after' data onto a floppy or print out the traces and attach it to a copy of the ECO and keep it with the product's compliance folder. I've had it for almost 2 years and haven't had a problem. John A.

RE: Agilent EMC analyzer
Gunter, We have an Agilent E7404A from the same family of Spectrum Analyzers. We have used it as a general EMI and signal integrity diagnostic tool. We have not run the built-in EMI pre-compliance reports. We like the fact that it is a digital instrument which is an improvement over the previous generation of analyzers. The digital design allows faster warm up times, more flexibility over allowable spans and bandwidths, and the built-in hard drive and floppy drive allow capture of data in a variety of formats for use in reports, or in further processing of the data. The built-in preamp is a convenient feature. Using previous models often required an external preamp and getting the gain factors right was always a pain. The ability to switch between AC or DC coupling is a feature that we find nice. We like ours. Jim _ Dr. Jim Knighten NCR Corporation http://www.ncr.com/ 17095 Via Del Campo San Diego, CA U.S.A.

ITU K.41
Hi All, I am hoping that someone has had some experience the interface definitions covered in the ITU K series recommendations. My question is regarding the interface references given as T1 and T2 in Table 1 of K.41. This is referring to the telecommunications interface, but it is not clear if the surge should be applied in common mode to all of the connections or if the reference is to a table of connections for 2 and 4 wire interfaces. Thanks in advance. Regards, Dave Spencer Oresis Communications
RE: Agilent EMC analyzer
We have several analyzers in this series and have nothing but good things to say about them. We even drag them out to our OATS and they survive the trips. Agilent is phasing out some of the EMC equipment, so make sure that you are not going to buy an orphan. At least make sure that they will continue to provide calibration and service if they do discontinue it.

RE: [Fwd: Police radar gun]
Dave, I disagree on your conclusion that a police radar gun is not a communication device. The device has a transmitter and a receiver and an automobile acts as a transponder. The device communicates with itself. However, even if the automobile is not present, the transmitter can be active and can potentially cause interference. This device acts no different than RFID and anti-theft products that read tags on products, railroad cars, cattle, cars, and ID badges. And these systems are definitely considered to fall under the RTTE directive. Your only potential out on this one is the public security exemption.

You won't find such things in any IEC standard (that's correctly written in accordance with the IEC Directives - some haven't been). IEC standards themselves are never mandatory - they are published to encourage the national standards committees to adopt them as national standards. When CENELEC adopts an IEC standard regionally, THEN it is compulsory for the national standards bodies of CENELEC member countries to adopt and publish it. At that stage, it is given a 'dow' - the date at which any earlier standard must be withdrawn. Mandatory compliance applies, even in CENELEC, only to standards used to demonstrate compliance with European Directives. The Commission, not CENELEC, then sets a 'docopocotss' (no, even the EC doesn't use such a crazy abbreviation) - 'date of cessation of presumption of compliance of the superseded standard' - which is normally the same as the 'dow' but need not be. Even then, compliance with standards MAY not be mandatory. For most Directives, there is an alternative 'route to compliance' that is more or less independent of any standards. The 'docopocotss' is normally set at 3 years after the publication of the standard, thus creating a 3-year transition period. -- Regards, John Woodgate, OOO - Own Opinions Only.

RE: New laser standards
Hi Folks WRT the IEC standard(s), as I understand it, IEC documents are - and always have been - "advisory documents" which only have "legal force" when they have been officially adopted in a particular country or region (e.g. the EU) by the relevant regulatory or standards body(ies) [ or adopted in contract between two companies]. It is those bodies which will mandate any transition periods that they consider appropriate. Thus, as far as the US is considered, the CDRH will be the relevant regulatory body. John Allen Thales Defence Bracknell UK -Original Message- From: Massey, Doug C. [mailto:masse...@ems-t.com] Sent: 11 June 2001 21:55 To: 'IEEE Forum' Subject: New laser standards Hello Group - Can anyone direct me to an informative article, link, etc., that summarizes the impact of Amendment 2 to IEC 60825-1, released in January of this year ? I've reviewed the amendment and am aware of the basic differences it brings in classification, but it sure would be nice to have a synopsis of all the changes. Also, does anyone know how soon the changes will be incorporated into a new release of the standard ? The IEC website does not list a target date for release, although the status of edition 1.2 shows it being out for printing since early May. Also, CDRH Laser Notice # 50, published late May, harmonizes, to some degree, 21CFR to the IEC 60825-1 standard, with the notable exception of production line test requirments, record keeping, and some product marking requirements, which are being kept by the CDRH. Has anyone heard if the CDRH product report formats will be changed ? I'm thinking an IEC-60825-1 report, with US national deviations, if you will, may be acceptable to the CDRH at some point in the future, in lieu of their existing published report format. Of greater concern is the lack of a specified transition period and mandatory compliance dates in either standard (at least I can't find them). Will existing laser classifications be grandfathered? When will laser product manufacturers be required to label products according to the new classifications? I can see the new classifications causing much confusion among customers, who may have, say, Class2 laser products, then buying additional units of the same product, which might be labeled as Class 2M, for instance.

Re: Wireless Network Issues
Kyle: Take a look at www.Intellon.com . They detail a link to some of the problems associated with proximity of Bluetooth devices to 802.11 LAN specs. These are claimed to be potential interference problems related to hop frequency differences in the two spread spectrum systems. There is also concern with the power line conducted control systems and the Continental Automated Building Associated attempted to address some of the issues related to compatibility during their conference held at the end of May. There are some 26 different standards all independantly developed which I'm sure is enough for a statistical study of the problem. There have been several papers on lack of EMC in hospitals - some originating from McGill University in Montreal. The main problem there seems to be lack of any emc equipment requirements ( although changing due to liability ) and the solution has been to isolate the areas containing the radio sensitive equipment. Tha Radio Advisory Board of Canada's EMC sub committee did address some concerns toward cable TV radiation and possible effects on some aircraft frequencies. With those problems largely overcome by regulating the cable operators , another issue has arisen and that could affect radio aids to navigation and it may have to do with radiation from home wiring above 2Mhz .. This is conceivable with ever increasing data rates and unshielded wiring. When I was chairman of the RABC EMC committee for a couple of years, there were many instances of life threatening incidences related to lack of EMC.

I've had to do this more blankety blank times, and can never find the reference when I want it UL, CSA, or TUV will frequently put an explicit reference to double-crimp connectors in their Section General, or in the "engineering" section of their technical files. That is "technical files" in a general sense, thank you. NOT necessarily a TCF or other formal EU document. Basically, you need to put two and two together. The regulations (almost every standard, almost every agency) generally state that certain safety-critical connections require "two independant means of protection." That is the trick phrase. In the case of insulation, of course, we are talking about double or reinforced insulation. In terms of connectors, this "two independant means" translates to: a) For soldered connections, wires must be looped through the terminal strip before soldering. b) For crimped connections, the insulation must be retained independantly of the conductor. To test, they tell you to pretend that one of the two means of retention has failed (i.e. the solder has melted or the conductor has broken). If the result could cause a hazard, then it fails. That's the story. Good luck finding specific references.

The shrink goes over the barrel of the contact / lug and the insulation of the wire. After shrinking / cooling the adhesive retains the wire pretty will. -Original Message- From: Gary McInturff [mailto:gary.mcintu...@worldwidepackets.com] Sent: Wednesday, September 20, 2000 9:40 AM To: 'Rich Nute'; andy.v...@mts.com Cc: emc-p...@majordomo.ieee.org Subject: RE: Double Retention Just adding to what Rich has said below about methods. The double crimp (or insulation crimp) is probably the best method because both crimps are made with the same tool at the same time so there is no manufacturing cost penalty, and several vendors supply the parts and I don't believe that there is any appreciable cost penalty for the parts. Simpler solutions are available if needed. You can tie one wire to the next with a wire tie for example. The first attachment point is the wire to connector pin, the second retention method then is the wire tie which is anchoring the wire itself to an adjacent pin, standoff or whatever. I prefer the first method for several reasons but wanted to point out the next most common, in my experience, method.

You might try PTB in Braunschweig Germany. I have witnesses them testing radar guns on the road in front of their laboratory.
