Richard Back in the old days when you had to certify non-intentional radiators I had a similar problem. I non-inductively bundled the offending radiating network signal cable so that it was very short, reducing the coupled signal below the limit. The FCC accepted the test report.
My recollection was that they were only concerned with what was being injected up the mains lead from the mains port on the EUT. regards Charlie Blackham -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: 06 December 2002 13:46 To: [email protected] Subject: Conducted Emissions Testing of Intentional Radiators When are testing a FCC Part 15 intentional radiator operating below 30 MHz, and have encountered the situation where the emissions from the antenna is being received by the power cord and causing the system to fail conducted limits. The transmitter complies with the conducted limits with a dummy antenna load. The transmitter has a detachable antenna and a 12 ft antenna cable. Is it permissible to demonstrate compliance with the conducted limits by 1) using a dummy antenna load, or 2) placing the antenna outside the chamber, or 3) some other way? Obviously, whatever method we use must be acceptable to the FCC.
