30、 IEC 60050-161, as well as 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 than the primary field components across any transverse cross-section 3.2 TEM waveguide ope

31、n or closed transmission line system, in which a wave is propagating in the transverse electromagnetic mode to produce a specified field for testing purposes. BS EN 62132-2:2011 6 62132-2 IEC:2010 3.3 TEM cell enclosed TEM waveguide, often a rectangular coaxial line, in which a wave is propagated in

32、 the transverse electromagnetic mode to produce a specified field for testing purposes. The outer conductor completely encloses the inner conductor 3.4 two-port TEM waveguide TEM waveguide with input/output measurement ports at both ends 3.5 one-port TEM waveguide TEM waveguide with a single input/o

33、utput measurement port NOTE Such TEM waveguides typically feature a broadband line termination at the non-measurement-port end. 3.6 characteristic impedance for any constant phase wave-front, the magnitude of the ratio of the voltage between the inner conductor and the outer conductor to the current

34、 on either conductor NOTE The characteristic impedance is independent of the voltage/current magnitudes and depends only on the cross-sectional geometry of the transmission line. TEM waveguides are typically designed to have a 50 characteristic impedance. TEM waveguides with a 100 characteristic imp

35、edance are often used for transient testing. 3.7 anechoic material material that exhibits the property of absorbing, or otherwise reducing, the level of electromagnetic energy reflected from that material 3.8 broadband line termination termination which combines a low-frequency discrete-component lo

36、ad, to match the characteristic impedance of the TEM waveguides (typically 50 ), and a high-frequency anechoic-material volume 3.9 primary (field) component electric field component aligned with the intended test polarization NOTE For example, in conventional two-port TEM cells, the septum is parall

37、el to the horizontal floor, and the primary mode electric field vector is vertical at the transverse centre of the TEM cell. 3.10 secondary (field) component in a Cartesian coordinate system, either of the two electric field components orthogonal to the primary field component and orthogonal to each

38、 other 4 General The IC to be evaluated for EMC performance is referred to as the device under test (DUT). The DUT shall be mounted on a printed circuit board (PCB), referred to as the EMC test board. The EMC test board is provided with the appropriate measurement or monitoring points at which the D

39、UT response parameters can be measured. The EMC test board is clamped to a mating port (referred to as a wall port) cut in the top or bottom of a transverse electromagnetic mode (TEM) cell. Either a two-port TEM cell or a one-port TEM cell may be used. Within this standard, a two-port TEM cell is re

40、ferred to as a TEM cell while a one-port TEM cell is referred to as a wideband (Gigahertz) TEM, or GTEM, cell. BS EN 62132-2:201162132-2 IEC:2010 7 The test board is not positioned inside the cell, as in the conventional usage, but becomes a part of the cell wall. This method is applicable to any TE

41、M or GTEM cell modified to incorporate the wall port; however, the measured response of the DUT will be affected by many factors. The primary factor affecting the DUTs response is the septum to EMC test board (cell wall) spacing. NOTE 1 This procedure was developed using a 1 GHz TEM cell with a sept

42、um to housing spacing of 45 mm and a GTEM cell with a septum to housing spacing of 45 mm at the centre of the wall port. The EMC test board controls the geometry and orientation of the DUT relative to the cell and eliminates any connecting leads within the cell (these are on the backside of the boar

43、d, which is outside the cell). For the TEM cell, one of the 50 ports is terminated with a 50 load. The other 50 port for a TEM cell, or the single 50 port for a GTEM cell, is connected to the output of an RF disturbance generator. The injected CW disturbance signal exposes the DUT to a plane wave el

44、ectromagnetic field where the electric field component is determined by the injected voltage and the distance between the DUT and the septum of the cell. The relationship is given by E = V/h where E is the field strength (V/m) within the cell; V is the applied voltage (V) across the 50 load; and h i

45、s the height (m) between the septum and the centre of the IC package. Rotating the EMC test board in the four possible orientations in the wall port of the TEM or GTEM cell is required to determine the sensitivity of the DUT to induced magnetic fields. Dependent upon the DUT, the response parameters

46、 of the DUT may vary (e.g. a change of current consumption, deterioration in function performance, waveform jitter, etc.) The intent of this test method is to provide a quantitative measure of the RF immunity of ICs for comparison or other purposes.

In addition,

48、the following test equipment requirements shall apply. 6.2 Cables Double shielded or semi-rigid coaxial cable may be required depending on the local RF ambient conditions. 6.3 RF disturbance source The RF disturbance source may comprise an RF signal generator with a modulation function, an RF power

49、amplifier, and an optional variable attenuator. The gain (or attenuation) of the RF disturbance generating equipment, without the TEM or GTEM cell, shall be known with a tolerance of 0,5 dB. BS EN 62132-2:2011 8 62132-2 IEC:2010 6.4 TEM cell The TEM cell used for this test procedure is a two-port TEM waveguide and shall be fitted with a wall port sized to mate with the EMC test board. The TEM cell shall not exhibit higher
