Book excerpt: Operating Long Range Radar Sites (LRRS) have reported that the Common Digitizer (CD) interferes with the Back-Up Emergency Communications (BUEC) equipments when the CD doors are OPENED for maintenance purposes. This problem was investigated. The investigation consisted of making Radio Frequency Interference (RFI) field strength measurements at various locations, both inside and outside the LRRS building as well as on the roof and radome catwalk. The measurements were made for various combinations of equipments being on with the CD doors both OPENED and CLOSED. It was determined that the CD with doors OPEN is the major source of RFI. The radiating source within the CD was traced to its core memory. With the CD doors CLOSED, RFI is reduced to negligible levels; furthermore, the roof of the building reduces the CD RFI to negligible proportions. (Modified author abstract).
