Hello Group, Some time ago (1996) in an email thread on absorbing clamps, Michael A. Royer stated that CISPR 14 defines a method for using current clamps instead of open area test sites. There was another thread for an on-site radiated emissions test when in noisy environments that mentioned using clamp-on probes.
Additionally I recall and article in one of the trade magazines (Compliance Engineering, ITEM, etc.) that described a method where a person could bundle all of the service connections for a product into an RF current clamp-on probe. The article also had information on converting the data on a spectrum analyzer into equivalent open area test site numbers. I would like to perform a test like this but have been unable to find a clamp-on probe that has at least a 100mm inner diameter and a frequency range of 30 MHz to 1000 MHz, possibly this is limited by physics. Is there anyone out there who is able to point me to articles or websites on: 1) RF current probe manufacturers. 2) The article and/or mathematical algorithm on measuring radiated emissions with current probe. 3) Application information. Thank you for any help you can provide. ================================== Doug Powell, Compliance Engineer Advanced Energy Industries, Inc.
