Derek, Absorbing clamp for use in the frequency range 30 - 1000 MHz is described in CISPR 16-1:1998, Section 13.
There were many attempts in CISPR SC G by Swiss and Swedish national committees to introduce absorbing clamp as the alternative test method to OATS for information technology equipment. Proposals were supported with numerous documents demonstrating correlation, but method was not adopted in CISPR SC G. Concession was made in CISPR 22, 2nd Edition, 1993, Section 12 Measurement of disturbance power, where clamp method was allowed in countries which already had provisions for using clamp in their national standards while subject remained under consideration. This provision was removed from CISPR 22, 3rd Edition, 1997. According to CISPR 16-1 absorbing clamps are suitable for the measurement of disturbance from some types of equipment. For example limit of disturbance power for household appliances and electric tools is set in CISPR 14. Mirko Matejic --------- This message is coming from the emc-pstc discussion list.
