Is there a practical way to have flush mounted receptacles in your turntable? Do you know how many different receptacles there are in the world? And what if I need to power a bunch or different equipment. Can you use a power strip according to CISPR 22? What is the logic behind this? Our power comes from a receptacle just inside the center of the turntable and it is bonded to the same ground as the turntable and ground plane. Why does it have to be ‘flush’? We test to CISPR11 which doesn’t have this requirement.
As far as C63.4, where does it talk about bore sighting the antenna? I couldn’t find it. I though a bore sight mast was only required with Horn antennas. Good stuff. This is the kind of information I keep an eye out for.

I’m talking about lab setups that aren’t in compliance with the standards. Simple things like power supplied to the EUT via a cord connected “somewhere” under the turntable, rather than via a receptacle flush with and bonded to the ground plane as required in CISPR 22 5th and 6th Editions. Or labs that have C63.4 in their Scope of Accreditation who don’t have a way to vary the angle of the antenna (bore sighting, if you will). Neither an automatic mast or a way to manually change the angle. How did this get by the assessor? I’ve been told it’s a new requirement. Yup, new in 1991. Give me a break. Ghery S.

Often it was because they didn't what was SUPPOSED to be done. We all learn from mistakes, eh?
