1 Scope and purpose

GB/T 17626 in this section gives a method of using a variety of TEM waveguide electronic and electrical equipment emission and immunity testing.

TEM waveguide with open (for example, stripline and electromagnetic pulse (EMP) simulators) and closed (for example, TEM chamber), may further Divided into single-port, dual-port and multi-port waveguide. TEM waveguide frequency range depends on the specific application of the test requirements and TEM waveguides Specific type.

The purpose of this section is given by.

--- TEM waveguide properties, including typical frequency ranges and limits on the size of the EUT;

--- Confirmation method for electromagnetic compatibility, TEM waveguide (EMC) test;

--- EUT (ie EUT housing and connection cable) definition;

--- Test arrangement radiated emission tests, procedures and requirements in the TEM waveguide;

--- Test arrangement radiated immunity test, the procedures and requirements in the TEM waveguide.

NOTE. Test methods specified in this part of the electromagnetic radiation device for immunity and radiated emission measurements are concerned. Simulation and measurement of electromagnetic radiation for Quantitatively determine the final installation EME use state is not accurate enough, the main purpose of the provisions of the test method is to ensure the qualitative analysis of electromagnetic effects the obtained test results of different test equipment used repeatability.

The purpose of this section is not applicable to test methods specified any particular product or system, but for all interested product committees Provide universal basic reference. For radiated emissions tests, the product should refer to the Commission the International Special Committee on Radio Interference (CISPR) Standard 1) select emission limits and test methods. For radiation immunity test, the Commission is responsible for the product selected equipment within its jurisdiction Select the appropriate test methods and immunity limits. This part of the test method described is independent of the GB/T 17626.32).

1) In the international electromagnetic compatibility standards, the standards for radiated emission test is part of CISPR standards.

2) Product Board, after consultation with "National Standardization Technical Committee on Radio Interference" and "National Standardization Technical Committee Electromagnetic Compatibility", and can be specified Using these different test methods.
