Dear all, Please help me to sort out this problem. While testing our equipment in the anechoic chamber in our place, we could notice that nearly 30db ambient noise present (say at 100Mhz) in the chamber before the equipment is tested. Then , if the our equipment fails at 100Mhz for 0.5 db does it really fail? Or if the equipment passes by 1 db margin, does it really pass ?
