Hello again: I would like some advise.
I have been doing Pre-compliance testing in a room at 3 meters, using corrected limits, with good results. The room has large windows behind the UUT and a lunch room an stock room to the side and hall and offices across the hall to the other side. Behind the antenna has been a room for storage. Do to business success the space is needed for more offices. So corporate is moving the lab. The new options are not as attractive. One adjacent room will have open development equipment at times for long periods, the problem! The outside wall is a cement block wall facing a woods not too bad, I think. The other side is a dock area, not too bad. The question is, I have recently read of using chicken wire , cheap, to suppress the ambient and prevent distracting ambient.. This is attractive to me, if it works, since some of the clocks in the development equipment will have the same clock frequencies I will be trying to monitor in the UUT. 1. How serious a problem can I expect from reflections? My correlation has been good to this point and we would like to maintain it. 2. Would it be better to fight the ambient, possibly missing some frequencies, or build the `economical' screen room? Any advice will be appreciated! Thanks! Best regards, Terry J.
