this subject is starting to get some momentum,which is a good thing to, to speak about lab experiences. My experience is the test lab has a job to do, they must know and interpret your prodcut by asking questions, then setup the EUT and cables per the standard, FCC/VCCI/EN55022 or another. They are not for OR against you, but only performing thier function. If a client ever feels like the lab is going over board, then they need to stop the scan and address the situation, because once its done, it cant be redone and then its just heresay. My main point is that during maximization, it needs to be done realistically and not turned into a rats nest. then the results will be born out. Crossing of power and signal cables intertwined would not be realistic, and thus wouldnt be maximized at the lab intertwined. regards to all. Richard,

They should be working with you not against you. John states it well. A big difference between doing the job well - maximizing etc - and trying to fail you.

Well, they are NOT supposed to, at least in Europe. This is over-zealous. It is required to make a reasonable attempt to maximize emissions under the restrictions imposed by the relevant standard, but an officious search for 'worst-worst-worst' conditions is not only not required, it is beyond the legal requirements. -- Regards, John Woodgate, OOO - Own Opinions Only.
