This Part is Part 9 of GB/T 33014. This Part is drafted in accordance with the rules given in GB/T 1.1-2009. This Part uses the redraft law to modify and adopt ISO 11452-9.2012 "Road vehicles - Component test methods for electrical disturbances from narrowband radiated electromagnetic energy - Part 9.Portable transmitters". The technical differences between this Part and ISO 11452-9.2012 and their reasons are as follows. - As for the normative references, this Part has made adjustments with technical differences, to adapt to the technical conditions of China. The adjustments are mainly reflected in Clause 2 “Normative references”. The specific adjustments are as follows. ⚫ Replace ISO 11452-1 with GB/T 33014.1, which modifies and adopts the international standard; ⚫ ADD reference to GB/T 33014.2-2016. - ADD notes to the numbers in Figure 6. - The figures in Table B.1 in the previous text are incorrect. This Part has made corrections. - The remote/local grounding in the previous text 7.2 adopts Annex D; this Part adopts the equivalent GB/T 33014.2-2016 Annex B, to avoid repetition of the same content. At the same time, delete Annex D. - Rearrange the frequency bands in Annex A of the previous text; GIVE a note for the international frequency bands not used in China; ADD some frequency bands used in China. - ADD annotations to Category 1, Category 2, and Category 3 in Annex C, to facilitate users' understanding and selection. This Part has made the following editorial changes. - In order to be consistent with China's technical standard system, change the standard name to "Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 9.Portable transmitters"; - According to the requirements of GB/T 1.1-2009, standardize the writing of Clause 1; - ADD the bibliography.

Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 9.Portable transmitters1 ScopeThis Part of GB/T 33014 specifies component test methods for electrical/electronic (ESA) disturbances from continuous narrowband radiated electromagnetic energy - portable transmitters.2 Normative referencesThe following documents are indispensable for the application of this document. For the dated references, only the editions with the dates indicated are applicable to this document. For the undated references, the latest edition (including all the amendments) are applicable to this document. 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 conditionsThe applicable frequency range of the portable transmitter method is 26 MHz to 5.85 GHz. The user shall specify the test severity level or levels over the frequency bands. The test severity level shall take into account5 Test locationThe test shall be carried out in an absorber-lined shielded enclosure. Basically, an absorber-lined shielded enclosure consists of a shielded room with absorbing material on its internal reflective surfaces, optionally excluding the floor. The design objective is to attenuate the reflected energy in the test area by at least 10 dB compared with the direct energy.6 Test instrumentationCommercial portable transmitters having an integral antenna are a convenient and readily available field-generating device. Signal sources with internal or external modulation capability. Power amplifier(s). multiple RF amplifiers may be required to cover the range of test frequencies.7 Test set-upEach DUT power supply lead shall be connected to the power supply through the power supply and an artificial network (AN). The total length of the test harness between the DUT and the load simulator (or RF boundary) shall not exceed 1700 mm. The load simulator shall be placed directly on the ground plane. If the load simulator has a metallic case, this case shall be bonded to the ground plane.8 Test methodsThe simulated portable transmitter antenna shall be placed at a minimum distance of 1 m from any part of the DUT, from the ground plane and from the test enclosure, and 0.5 m from any absorber. It shall use unmodulated sinusoidal wave for calibration. During calibration, the adjustment of the net power shall be performed, until the predetermined level is achieved.Annex A(Informative) Typical characteristics of portable transmitters Examples of typical characteristics of portable transmitters are given in Table A.1, and an explanation of the terms used is given in Table A.2. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
