Shock and Vibration
Hi All, Does anyone know what IEC 48D (Secretariat) 76 would be? It is called out in the IEEE 1386:2001 standard for CMC cards as shock and vibration requirements. I assumed that IEC 48D was a standard but apparently that is not the case. SC 48D is a Subcommittee dealing with Mechanical Structures for Electronic Equipment; so I'm thinking that IEC 48D (Secretariat) 76 is the proceedings from one of their meetings but I have had no luck in locating any information about it. My Marketing gurus are asking me if we meet these requirements but I don't know what the requirements are; so its kind of hard to give them an answer. :-) Thanks for your help.

European environmental standard
Hi All, My apologies if this is slightly off topic for this list but I thought that, with the wealth of knowledge out there, this would be a good place to start. Has anyone out there had any experience with testing a product for compliance to IEC 60721-3 (Classification of environmental conditions. Part 3: Classification of groups of environmental parameters and their severities)? It has three sections that deal with Storage, Transportation and Stationary use at weather protected locations. My first thought was that possibly it was referenced in GR-63-CORE since it deals with environmental issues but it is not. I am prepared to buy the standard if necessary but I am trying to determine if there is an actual test regime that is specific to this standard or if it would be covered within another standard. Our normal test lab wasn't aware of a test program for this standard; so I thought I'd toss it into this arena. BTW the product here is a PMC module with one ethernet port and falls under the ITE category. Any information will be greatly appreciated. Thanks in advance!

RE: UL2725 UL2835 on USB cables
Brian, When you checked with UL did you mention that these numbers were on cables? 2725 and 2835 are AWM Style numbers. If you go to UL's web site and click on Customers and then Wire and Cable and look under AWM Styles you can do a search for specific style numbers, file numbers etc. This will give you information about the specific style numbers.

RE: ISN or Current probe method on telecommunication ports?
Richard, For shielded ports/cables the method used should be the current clamp method as described in C.1.2 of Annex C, EN 55022:1998. The ISN is used for unshielded ports/cables. We had the same problem of failing conducted emissions when we used an ISN. When you put a current clamp on a shielded cable you are seeing the data return currents on the shield. Connecting the shield to earth through a 150 ohm resistor as specified in C.1.2 compensates for that. At least that is my understanding; maybe others have more insight into this.

Dear Colleague, Does anybody have done any conducted emission test on telecommunication ports per EN55022 1998 standard requirement? Currently, we have performed a conducted emission test of our product on the shielded telecom port by using ISN and current probe methods, and the results of both tests are totally different. With ISN method, the EUT failed the conducted emission on shielded telecom port by 20 dB. With current probe method, our product passed the conducted test with good margin. We don't know what is the theory behind the ISN and Current probe methods? Can anybody explain to us or advise what we need to do to pass the conducted emission test? Can the test lab accept the current probe method test data or we have to meet both limits of voltage and current requirements that listed in table 4 of CISPR. 22 1997 standard? Our product used all shielded cables on telecom ports. Per Clause 9.5.3.3 9.5.3.4 of CISPR. 22 1997, both methods are allowed for telecom port testing. Any suggestions or feedback will be very appreciated. Thanks in advance!

compactPCI bus
Judging from the number of responses (0) I got to my question about EMI problems from compactPCI backplanes I am assumiong that either no one uses cPCI backplanes or I'm the only one that has experienced problems when testing in this environment. I didn't think that ever happened in this group. I'll repost this just in case some of you didn't get the last one. This is a question regarding systems which use CompactPCI bus architecture. On a cPCI backplane the PCI clock is routed to every slot on the backplane with up to 7 peripheral slots possible on a normal backplane. My question is this: With the cPCI specification calling out specific trace lengths for clock traces on both the backplane itself and on peripheral cards, have other people experienced any unique EMI problems in trying to meet the design constraints associated with this synchronous bus; especially where there are unpopulated slots on the backplane? Please feel free to respond privately if the question is unclear. I wasn't sure if it was worded properly.
