33、ng an absorbing clamp is a method for the determination of the radiated disturbance in the frequency range above 30 MHz. This measurement method represents an alternative approach to the measurement of the disturbance field strength on an OATS. The absorbing clamp measurement method (ACMM) is descri

34、bed in Clause 7 of CISPR 16-2-2. The ACMM uses the following measurement instrumentation: the absorbing clamp assembly; the secondary absorbing device; the absorbing clamp test site. Figure 1 gives an overview of the absorbing clamp measurement method including the instrumentation required for this

35、method and the calibration and validation methods for the instrumentation. The requirements for the instrumentation necessary for the ACMM are specified in this clause. Details of the absorbing clamp calibration method, and validation of other properties of the clamp and the secondary absorbing devi

36、ce, are described in Annex B. Details of the absorbing clamp test site validation are described in Annex C. Absorbing clamps are suitable for the measurement of disturbances from some types of equipment, depending on construction and size. The precise measuring procedure and its applicability is to

37、be specified for each category of equipment. If the EUT itself (without connecting leads) has a dimension that approaches 1/4 of the wavelength, direct cabinet radiation may occur. The disturbance capability of an appliance having a mains lead as the only external lead may be taken as the power the

38、appliance could supply to its mains lead, which acts as a transmitting antenna. This power is nearly equal to that supplied by the appliance to a suitable absorbing device placed around the lead at the position where the absorbed power is at a maximum. Direct radiation from the appliance is not take

39、n into account. Equipment having external leads other than a mains lead can radiate disturbance energy from such leads, whether shielded or unshielded, in the same manner as radiation from the mains lead. Measurements using the absorbing clamp can be made on these types of lead as well. The applicat

40、ion of the ACMM is specified in more detail in 7.9 of CISPR 16-2-2. 5 EN 55016-1-3:2006Licensed Copy: Wang Bin, na, Mon Mar 26 08:08:30 GMT+00:00 2007, Uncontrolled Copy, (c) BSI4.2 The absorbing clamp assembly 4.2.1 Description of the absorbing clamp assembly Annex A describes the construction of t

41、he clamp and gives a typical example of such a construction. The absorbing clamp assembly consists of the following five parts: a broadband RF current transformer; a broadband RF power absorber and impedance stabilizer for the lead under test; an absorbing sleeve and assembly of ferrite rings to red

42、uce RF current on the surface of the coaxial cable from the current transformer to the measuring receiver; a 6 dB attenuator between the output of the absorbing clamp and the coaxial cable connecting to the measuring receiver; a coaxial cable as receiver cable. The clamp reference point (CRP) indica

43、tes the longitudinal position of the front of the current transformer within the clamp. This reference point is used to define the position of the clamp during the measurement procedure. The CRP shall be indicated on the outside housing of the absorbing clamp. 4.2.2 The clamp factor and the clamp si

44、te attenuation An actual measurement of an EUT using the ACMM is depicted schematically in Figure 2. Details on the ACMM are given in Clause 7 of CISPR 16-2-2. The disturbance power measurement is based on measurement of the asymmetrical current generated by the EUT, which is measured at the input o

45、f the absorbing clamp using a current probe. The absorbing ferrites of the clamp around the lead under test isolate the current transformer from disturbances on the mains. The maximum current is determined by moving the absorbing clamp along the stretched lead, which acts as a transmission line. The

46、 transmission line transforms the input impedance of the absorbing clamp to the output of the EUT. At the point of optimal adjustment, the maximum disturbance current at the current probe or the maximum disturbance voltage at the receiver input can be measured. For this situation the actual clamp fa

47、ctor CFact of an absorbing clamp relates the output signal of the clamp Vrec to the measurand of interest, i.e. the disturbance power Peutof an EUT as follows: Peut = CFact+ Vrec (1)where Peut = the disturbance power of the EUT in dBpW; Vrec = the measured voltage in dBV;CFact = the actual clamp fac

48、tor in dBpW/V. Ideally, the received power level Prec in dBpW at the receiver input can be calculated using the following formula: () 17log10recirecrec= VZP V (2) 6 EN 55016-1-3:2006Licensed Copy: Wang Bin, na, Mon Mar 26 08:08:30 GMT+00:00 2007, Uncontrolled Copy, (c) BSIwhere Zi= 50 , input impeda

Using Equations (1) and (2) one can derive a relation between the disturbance power Peut emitted by the EUT and the power Precreceived by the receiver as follows: 17actreceut+= CFPP (3) This ideal relation between the disturbance power of the EUT and the power received by the measuring receiver is defined as the actual clamp site attenuation Aact(in dB). 17actreceutact+=
