Hi,here is some info perhaps useful for you: 1.I've heard some certain probe which inner diameter is up to 300mm.But I haven't see its details,nor know its frequency span.
2.FCC Inc. once produces some probes.Here is its address: FISCHER CUSTOM COMMUNICATIONS,INC 3121 West 139th Street, Unit F Hawthorne, CA 90250. FAX:(310)644-2452 3.I know some articles concerned about what you've mentioned.I list them below: N.J.CarteríóE.G.Stevestí+An improved EMC specification for aerospace equipmentí+ú?IERE international conference on EMC 1984íú N.J.Carterí+Requirement for the vulnerability test of military aircraftí+ú?REA Report No.87-0014íú N.J.Carterí+The development of a revised susceptibility test for avionic equipmentí+ú?IERE international conference on EMC 1982íú N.J.Carterí+The EMC testing of aircraft equipmentí+ú?AD/A 105093íú í+RTCA/D0-160cí+ú?section 20ú?ISO 7137ú+íú D.A.BullíóN.J.Carterí+Test civil aircraft and equipment to the new external Rf environmental conditionsí+íú John W.

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.
