Gary, I have had my problems with support equipment and peripherals also. And, having used a lot of big name products, mostly computers, etc., I was surprised at how many of them failed when my product was turned off and theirs was left running. It is quite common for test house guys to say " Oh, that's the host, we'll ignore that one". I finally got to the point where I put them outside the test environment, i.e. below the floor or outside the shield room. I do this because I don't sell them and figure that if I run self test mode and don't see the problem, then it is either the other guy's stuff or my I/O. If it is my I/O, I will fix it. If it is the other guy's stuff, I leave it alone. I can't / won't fix their non-compliant equipment, don't have either the time or money to do so. I did eventually find a quiet PC and monitor which I guard with my life. I have even coerced the software guys into making their latest stuff play with my older PC so I can keep using it.
I can't point to the reference you are asking for. It seems to me that if the support / host equipment is required to be on the table during test, then the entire thing must comply. It can be difficult to point the finger at one piece and say that it is the source of the problem, especially on the immunity side. If you try several different pieces of support equipment and the "system" continues to fail, it probably is within the common unit, i.e. your product. If you find that changing the support equipment can make the "system" pass, then either you have a marginal product or a too-sensitive support equipment. In this case, you have a decision to make, and a tough one at that. Sorry I am not more help on this one.
