Mark,
The work discussed in CISPR/I/89/CD ultimately failed. This has not resulted in any amendments to CISPR 22. There is a new Task Force under CISPR SC I working on this matter, but they are starting from scratch. Ghery S. Pettit Co-convenor, CISPR SC I WG3 _____ From: [email protected] [mailto:[email protected]] On Behalf Of Mark Gandler Sent: Monday, November 28, 2005 5:23 PM To: [email protected] Subject: Conducted Emission testing for Ethernet over power line product. Hi Group, I am looking for an opinion regarding an interpretation and implementation of CISPR I/89/CD. Let's say you have a product that can transmit Ethernet over power lines in your house (this is not power over Ethernet). This could be considered as Power Line Communication with Multi Purpose Port (AC main + data). If we would have followed old CISPR22 methodology for testing conducted emission, while Ethernet is transmitting, it would've fail (just to make sure, it did fail) at 5Mhz-30Mhz range. So IEC recognized the problem and come up with some amendments to CISPR22 and I believe it is still a life document. It is my understanding, that based on those amendments, for PLC product, Cond. Emis. has to be tested in 2 ways: 1)old way with LISN, data Tx is off, regular CE AC limits; 2)with Tx on, with TISN, against Telecomm limits. Is my understanding correct? If yes, is there TISN for 240V and if there someone out there, who actually did this test already?
