All, I've been reading through past posts on GTEM cells. The limitation that seems to be mentioned the most is the difficulty in cable manipulation/ cabling being part of the finite EUT test volume available limits the accuracy/ correlation of test data below 230 MHz. I'm looking into purchasing GTEM cells as a supplement to our anechoic chamber. They are appealing due to the fact that they are cheaper and we can fit sveral of even the largest TEM cell in the area taken up by one chamber. My first question would be whether practical solutions to the cable manipulation issue have been identified and if so what is it?
I also know that the reading from the septum varies depending on location in the test area. What is the group's experience with repeatability from emissions scan doing repeated test on the same product? I'm just trying to get a feel for how practical TEMs are for emissions testing. Any information you could provide me would be appreciated. Thank you. Regards, John P.
