Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 3.Transverse electromagnetic (TEM) cell1 ScopeThis Part of GB/T 33014 specifies the immunity test for electrical/electronic components to continuous electrical disturbances from narrowband radiated electromagnetic energy - transverse electromagnetic (TEM) cell.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the dated edition cited applies. For undated references, the latest edition of the referenced document (including all amendments) applies. GB/T 33014.1 Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 1.General (GB/T 33014.1-2016, ISO 11452-1.2005, MOD)3 Terms and definitionsFor the purposes of this document, the terms and definitions given in GB/T 33014.1 apply.4 Test conditionsFor transverse electromagnetic (TEM) cell, the useful frequency range is 0.01 MHz to 200 MHz. The upper frequency range limit of the TEM cell is a direct function of the TEM cell dimensions. See annex A for suggested cell dimensions.5 Test apparatus and instrumentationThe TEM cell used for this test is a rectangular coaxial line with a 50 Ω characteristic impedance (see Figure 1). The device under test (DUT) is exposed to a uniform TEM field. The shield shall be in electrical contact with the cell floor, but shall not be in contact with the case of the DUT.6 TestPrior to performing the test, a test plan shall be generated which shall cover the following. Make a net, or output, power (see Figure 2) measurement and calculate the electric field using equation 1. As required by the test plan, a test report shall be submitted detailing information on the test equipment used, systems tested, frequencies, power levels, system interactions and other relevant information regarding the test.Annex A(informative) TEM cell dimensions The dimensions of a typical TEM cell are shown in Figure A.1 and given in Table A.1. Dimensions in millimetresAnnex B(informative) Calculations and measurements of TEM-cell frequency range The useful frequency range for each TEM cell and its test set-up can be determined by one of two methods using instrumentation (e.g. a network analyzer).Annex C(informative) Installation of external components and low pass filter design The wiring in the connector panel between connector and the coaxial connectors shown in Figure 3 shall be done with 50 Ω coaxial cable to transfer the 50 Ω RF- impedance from the low pass filters attached to the coaxial connectors in the connector panel to the connector in the TEM cell wall.Annex D(informative) Function performance status classification (FPSC) Suggested test severity levels and the frequency bands of this Part are given in Table D.1 and Table D.2, respectively. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
