29、of this document, the terms and definitions given in IEC 62132-1:2006, Clause 3, IEC 60050-131 and IEC 60050-161, and the following, apply. 3.1 transverse electromagnetic mode TEM waveguide mode in which the components of the electric and magnetic fields in the propagation direction are much less th

31、g purposes 3.3 IC stripline TEM waveguide, consisting of an active conductor placed on a defined spacing over an enlarged ground plane, connected to a port structure on each end and an optional shielded enclosure BS EN 62132-8:201262132-8 IEC:2012 7 Note 1 to entry: This arrangement guides a wave pr

32、opagation in the transverse electromagnetic mode to produce a specific field for testing purposes between the active conductor and the enlarged ground plane. The ground plane of the standard EMC test board according to IEC 62132-1:2006, Annex B, should be used. An optional shielding enclosure may be

33、 used for fixing the IC stripline configuration and for shielding purposes. This leads to a closed version of the IC stripline in opposite to the open version without shielding enclosure.

For further information and equation to stripline arrangements see Annex A. 3.6 primary field component primary component electric field c

37、erformance is referred to as a device under test (DUT). The DUT should be mounted on an EMC test board according to IEC 62132-1. The EMC test board is provided with the appropriate measurement or monitoring points at which the DUT response parameters can be measured. It controls the geometry and ori

38、entation of the DUT relative to the active conductor and eliminates in the case of a closed version of the IC stripline any connecting leads within the housing (these are on the backside of the board, which is outside the housing). For the IC stripline, one of the 50 ports is terminated with a 50 lo

39、ad. The other 50 port is connected to the output of an RF disturbance generator. The injected RF disturbance signal exposes the DUT to an electromagnetic field determined by the injected power, the typical impedance and the distance between the ground plane of the EMC test board and the active condu

40、ctor of the IC stripline. The relationship is given in Annex A. Rotating the EMC test board in the four possible orientations in the aperture to accept EMC test board of the IC stripline will affect the sensitivity of the DUT. Dependent upon the DUT, the response parameters of the DUT may vary (e.g.

41、 a change of current consumption, deterioration in function performance, waveform jitter). The intent of this test method is to provide a quantitative measure of the RF immunity of DUTs for comparison or other purposes. For further information see Annex A. 5 Test conditions 5.1 General The test cond

42、itions shall meet the requirements as described in IEC 62132-1:2006, Clause 4. In addition, the following test conditions shall apply. BS EN 62132-8:2012 8 62132-8 IEC:2012 5.2 Supply voltage The supply voltage shall be as specified by the IC manufacturer. If the users of this procedure agree to oth

43、er values, they shall be documented in the test report. 5.3 Frequency range The effective frequency range of this radiated immunity procedure is 150 kHz to 3 GHz. 6 Test equipment 6.1 General The test equipment shall meet the requirements described in IEC 62132-1:2006, Clause 5. In addition, the fol

44、lowing test equipment requirements shall apply. 6.2 Cables Double shielded or semi-rigid coaxial cable may be required depending on the local ambient conditions. 6.3 Shielding Testing in a shielded room is only necessary for the open IC stripline version. The closed version of the IC stripline is sh

45、ielded by its housing. 6.4 RF disturbance generator An RF disturbance generator with sufficient power handling capabilities shall be used. The RF disturbance generator may comprise an RF signal source with a modulation function, an RF power amplifier. The voltage standing wave ratio (VSWR) at the ou

46、tput of the RF disturbance generator shall be less than 1,5 over the frequency range being measured. The gain (or attenuation) of the RF disturbance generating equipment, without the IC stripline, shall be known with an accuracy 0,5 dB. 6.5 IC stripline The IC stripline (open or closed version) used

47、 for this test procedure shall be fitted with an aperture to mate with the EMC test board. The IC stripline shall not exhibit higher order modes over the frequency range being measured. For this procedure, the IC stripline frequency range is 150 kHz to 3 GHz. The VSWR over the frequency range of the

48、 empty IC stripline being measured shall be less than 1,25. For further information as to field strength determination, IC stripline designs and the limitation of geometrical dimensions of closed version, see Annexes A, B and C. 6.6 50 termination A 50 termination with a VSWR less than 1,1 and suffi

49、cient power handling capabilities over the frequency range of measurement is recommended for the IC stripline 50 port not connected to the RF disturbance generator. 6.7 DUT monitor The performance of the DUT shall be monitored for indications of performance degradation. The monitoring equipment shall not be adversely affected by the injected RF disturbance signal. BS EN 62132-8:201262132-8 IEC:2012 9 7 Test setup 7.1 General A test setup shall meet th
