ABSTRACT:
The RFI generated by a piece of electrical or electronic equipment is meaed by placing the equipment within a screened test room. A pick-up antenna within the room generates a signal which, after filtering and amplification, drives a reference antenna in a second screened room which is identical to the first. A second pick-up antenna in the first room and a corresponding antenna in the second room are connected to a comparator which compares the RF field intensity in both rooms.
