RE: Bellcore GP-1089 emissions testing: LISN test setup
Patrick - Bypass caps were used in an older version of 1089, and subsequently replaced with LISNs in the current version. Regards, Mark Gill, P.E.

RE: Bellcore GP-1089 emissions testing: LISN test setup
I seem to remember the caps were specified in an earlier version of the standard, and are no longer required (issue 2, rev 1 February 1999). My understanding is that the LISN is that used for CISPR measurements.

Re: WEEE directive (4th Draft)

SAE testing
Group, I have an In-Vehicle Computer (ITE equipment) that will be implemented into heavy duty trucks. I am unfamiliar with SAE requirements and only have been told that I will have to be compliant to J1455. I am looking for some clarification on if this is the correct standard, (if it is not then what is) and if this is a compliance issue that has to be addressed or if testing is a matter of choice.

Probe ground leads
Hi All, Here is some light reading if you are looking for a way to pass a hot day (it is 109 degrees here in Los Gatos today!) Often, a probe ground lead is thought of as a source of error in a measurement. But, the ground lead can also increase measurement accuracy. I have posted a supplemental Technical Tidbit for June at www.dsmith.org on probe ground leads. It located at the bottom of the index page just below the main Technical Tidbit for June on 180 degree combiners. Doug -- --- ___ _ Doug Smith \ / ) P.O.
