Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 7.Direct radio frequency power injection

1 Scope

This Part of GB/T 33014 specifies component test methods for electrical/electronic disturbances from continuous narrowband radiated electromagnetic energy - direct radio frequency power injection.

2 Normative references

The 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 definitions

For the purposes of this document, the terms and definitions given in GB/T 33014.1 apply.

4 Test conditions

The user should specify the test severity levels over the frequency range (see Annex B). These levels are expressed in terms of the equivalent root-mean- square value of the unmodulated sine wave.

5 Test facility

Figure 1 shows an example of a set-up of a direct RF power injection measurement system. The spectrum analyzer or power meter shall be capable of measuring levels provided by the sampling device with an uncertainty of ± 1 dB. If necessary to preclude interference with other test activities, this test shall be performed in a shielded room.

6 Test method

When required in the test plan, a test report shall include information regarding the test equipment, test site, systems tested, frequencies, power levels, interactions of sub-systems tested and any other information relevant to the test.

Annex A

(Informative) Broadband artificial network (BAN) design An example schematic and assembly drawing is shown in Figure A.1.

Annex B

(Informative) Function performance status classification (FPSC) This annex gives examples of test severity levels. For detailed description of FPSC, see GB/T 33014.1. ......
