Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 3: Transverse electromagnetic (TEM) cell 1 Scope This part of GB/T 33014 specifies the component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy with transverse electromagnetic (TEM) cell This part is applicable to electrical/electronic components for Categories M, N, O and L vehicles, regardless of the vehicle propulsion system, (e.g. spark-ignition engine, diesel engine, electric motor). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any 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) GB/T 33014.2 Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 2: Absorber-lined shielded enclosure (GB/T 33014.2-2016, ISO 11452-2: 2004, MOD) 3 Terms and definitions For the purpose of this document, the terms and definitions given in GB/T 33014.1 apply. 4 Test conditions The applicable frequency range of transverse electromagnetic (TEM) cell 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 TEM cell dimensions and Annex B for calculations and measurements of TEM-cell frequency range. The users shall specify the test severity level(s) over the frequency range. See Annex D for suggested test severity levels. The following standard test conditions shall meet the requirements of GB/T 33014.1: ——test temperature; ——test voltage; ——modulation; ——dwell time; ——frequency step sizes; ——definition of test severity levels; ——test signal quality. 5 Test apparatus 5.1 TEM cell The TEM cell used for this test is a rectangular coaxial line with a 50 Ω characteristic impedance (see Figure 1). The device (DUT) under test is exposed to a uniform TEM field. The TEM cell is a laboratory measurement system which can be used to generate test fields within 2 dB of the theoretical value if the device under test does not occupy an excessive portion of the test volume (see 5.3).   Key: 1——outer conductor (shield); 2——septum (inner conductor); 3——access door; 4——connector panel (optional); 5——coaxial connectors; 6——dielectric support; 7——DUT; 8——input/output leads Figure 1 TEM cell 5.2 Instrumentation Figure 2 shows an example of a TEM cell test set-up. The TEM cell has high resonances in the region greater than the suggested upper frequency limit. A low pass filter with an attenuation of at least 60 dB at frequencies above 1.5 times the cut-off frequency of the TEM cell (see Annex C) shall be installed to avoid resonances (e.g. 200 MHz TEM cell: 60 dB for frequencies above 300 MHz).

Figure 2 Example TEM cell configuration 5.3 Test set-up 5.3.1 General In order to maintain the homogeneous field in the TEM cell and obtain reproducible measurement results, DUT shall be no larger than one-sixth of the cell (inside) height, b. The DUT shall be placed in the center of the cell on a dielectric equipment support (εr≤1.4). The DUT and the wiring harness may be positioned in either of two arrangements, depending on whether the exposure of the DUT and the wiring harness (5.3.2) or that of the DUT alone is being tested. 5.3.2 Exposure of DUT and wiring harness (for major field coupling to the harness) The height of the dielectric support is one sixth of cell height b (see Figure 3). In order to obtain reproducible measurement results, the DUT together with its wiring harness or printed circuit board shall be placed in the same position in the TEM cell for each measurement. In addition to the direct RF-field coupling to the device under test, the use of an unshielded harness or printed circuit board will result in a common mode electrical field coupling and a differential mode magnetic field coupling, depending on the inclination and the width of the harness or circuit board.
