Mexico requirements
To all, If a manufacturer of an FCC Part 18 device (ISM) wants to sell in Mexico, what are the procedures for meeting the Mexico standards? Is the MRA in sight? I know of the Telecom NOM's, but not about ISM equipment procedures. This is the first time we've had this inquiry, so any information would be helpful. Thanks to all.

RE: cable maximization - do you or don't you??
Charles, I applaud your integrity! You are right to insist on maximization of cable placement when performing emissions testing. The ANSI document does indeed call this out, and the cable placement, as well as the peripheral equipment placement, should be maximized, of course while staying within the boundaries of the ANSI C63.4 definition and typical installation/setup of the EUT. As you know, the idea is to investigate the worst case emissions from the system (EUT) within the typical parameters of use of the EUT. Some laboratories do not do this because it may be difficult and time-consuming, but they are doing you a disservice. Continue to insist that your lab/OEM supplier follows the ANSI C63 test setup and procedures.

In order to declare conformity to New Approach Directives, the manufacturer places the CE mark on the product and issues a Declaration of Conformity. How does a manufacturer declare compliance to the WEEE/RoHS? The RoHS Directive is basically a legal requirement that certain substances are not used and is therefore just like other legislation. No CE mark is necessary. The WEEE Directive is more specific to specified industrial sectors basically specifying how waste and its recovery is to be dealt with. Again, no CE mark is necessary. A Directive still under discussion is the Eco-design of End Use Equipment. This is to present a framework for the integration of environment aspects in the design and development and for setting eco-design requirements This will require conformity assessment against harmonised standards. Presumably a Technical File must be produced to contain data that details environmental characteristics and performance of a product, disposal at end-of-life, the ecological profile of the product, etc...

RE: cable maximization - do you or don't you??
Hi All, my comment might not fit exactly into this thread but during my tests I made the observation that on some EUTs the emissions got worse when cables were removed. This happened mostly in the frequency range beyond 300MHz but also below. For the moment I have two theories on that: There are cancellation effects on the critical frequencies with the full cable configuration. The fact that a cable is attached or not influences the common-mode currents on the surface of the enclosure in direction and magnitude. This makes some slots in the enclosure more or less efficient antennas depending on the current in that area. The first theory suits more for the low-frequency range (300MHz) in my eyes and the second one for the rest. I am chewing on that one for a little while but neither have the time nor the means to explore these theories further. I am curious on your comments. For the moment these are just theories ... Any similar experiences? Best regards, Michael -Original Message- From: Charles Grasso [mailto:cgrassospri...@earthlink.net] Sent: Dienstag, 8.

Re: cable maximization - do you or don't you??
I read in !emc-pstc that Ken Javor ken.ja...@emccompliance.com wrote (in bb2f7186.2be2%ken.ja...@emccompliance.com) about 'cable maximization - do you or don't you??' on Mon, 7 Jul 2003: I don't think it is at all complicated, at least in principle. Maybe a devil will emerge out of some details I am missing... It's a point worth discussing. I don't see how an end-driven wire can radiate more efficiently than a tuned half-wave dipole. That model can be used to convert from field intensity at X meters to peak current on the cable. Agreed that it can't be more efficient, but it can be less efficient to a nearly unlimited extent, so making that assumption can be very pessimistic indeed. For the case of multiple cables one could make various assumptions about the additive effect of emissions at X meters: A worst case assumption is that the same spectrum could appear on each cable and add in phase at the measurement point. This would require subtracting from the previously determined single cable current limit the factor: 20*log (number of cables). I think this is unreasonable, that the summing would be of random phase and the factor to be subtracted from the single cable current limit ought to be 10*log (number of cables). Agreed, as a first approximation. I am not trying to say that this approach is precisely correct and should be implemented as is. I do think it would be interesting to make some cable measurements using an absorbing clamp and compare to the corresponding OATS profile and draw some conclusions. Yes, I think that is justified, now that you have raised the subject. Unfortunately, many such proposals are never investigated because no-one has the time, even if the costs can be handled. I think we all look forward to your report of the first results.

Re: EU Language Requirements
Bob, Compliance with translation requirements for safety is a regulatory requirement in many countries within the EU, but you are presumably not talking safety for your software interface? This means that primarily you are concerned with supplying a product that carries out a particular function after your customer has interfaced with the software in some way. Perhaps for the US market you have menus for your customers to follow and perhaps a help menu in case they get stuck? Consider that you were trying to sell two products having identical functionality in the US marketplace, one was available in American English only whereas the other was only available in Danish (or other language if you'd prefer): by what percentage would the English product outsell the Danish one? Even if the English language product did not exist, how much of an uphill struggle would it be to sell a Danish only product? Of course, in certain technical areas it may be that you could expect customers to have a reasonable grasp of the English language, but that is specific to your potential customer base and is something that you will need to address in your marketing strategy. You also ask about warrantees. Here you need to look not only at legislation dealing with language itself but also about legislation regarding implied terms in contract. In the consumer area at least there is legislation that effectively null and voids unreasonable terms in contracts (such as exist when you purchase a piece of software from a high-street shop and install it on your PC at home). However, if you wanted to include a limitation which (let us say) is considered to be reasonable if written in the language of the country concerned, then would it be worth the paper it was printed on if it were in a foreign language - I rather suspect it wouldn't? Regards, Richard Hughes Safety Answers Limited
Monitoring Random ESD events
I'm pretty new to the EMC scene and I need to monitor a product to see what kind of ESD events it generates on its own. The customer wants me to attach my oscope to their sensors and see what kind of ESD voltages their sensors see in daily operation. I know that I don't want to directly connect the oscope to the sensors while the machine is running. I was trying to figure out a way to isolate the signals on the sensors from the oscope but still get a value that is useful. I was thinking of some sort of current loop around the sensor wires. How would I correlate the current loop measurement to an ESD voltage? I'm probably not providing enough information but I'm not really sure what information will be needed.

However, I need a slightly more sophisticated package that will allow me to dump screens as plots at 15 minutes intervals over a prolonged period unto a laptop using GPIB. I envisage using an Advantest 3265 or HP 8562 analyzer
Shipments into Japan
I have recently been told that product going into Japan for sale must have the importers name on the label and the imported MUST be registered with METI (Ministry of Economy, Trade and Industry). Has any one come up with this same requirement? What constitutes and importer?

RE: Monitoring Random ESD events
Eric: First, do not attach your scope (via probes) to the EUT if it generates a static charge on its own. First, it is possible to blow the front end of your scope, and secondly, a 10 Mohm impedance will probably be low enough that any charge cannot build-up to the level you want to measure.

The customer wants me to attach my oscope to their sensors and see what kind of ESD voltages their sensors see in daily operation. I know that I don't want to directly connect the oscope to the sensors while the machine is running. I was trying to figure out a way to isolate the signals on the sensors from the oscope but still get a value that is useful. I was thinking of some sort of current loop around the sensor wires. How would I correlate the current loop measurement to an ESD voltage? I'm probably not providing enough information but I'm not really sure what information will be needed.

Re: Monitoring Random ESD events
If you can get near the sensors (1 inch), 3M makes a static field meter. Their Model 718 is a non-contact device and has an analog output proportional to the field for logging.

It has a lab windows flavour to it so you basically write a flow chart of what you want to do. What you describe would take about a half hour to set up. If you'd like to know more perhaps we should chat offline. Cheers, Derek N. Walton Owner L F Research EMC Design and Test Facility Poplar Grove, Illinois, USA www.lfresearch.com
