Scope

This part of GB/T 17626 gives the methods for the emission and immunity tests of electronic and electrical equipment using various TEM waveguides. TEM waveguides are available as open (e.g., stripline and electromagnetic pulse (EMP) simulators) and closed (e.g., TEM chambers), and can be further classified as single-port, dual-port, and multiport waveguides. The applicable frequency range of the TEM waveguide depends on the specific test requirements and the specific type of TEM waveguide. The purpose of this standard is to give: - the performance of TEM waveguides, including typical frequency ranges and limitations on the size of the EUT; - the verification method for TEM waveguides for electromagnetic compatibility (EMC) tests; - the EUT (ie EUT housing and connecting cables); - test arrangement, procedures and requirements for radiated emission tests in TEM waveguides; - test arrangements, procedures and requirements for radiated immunity tests in TEM waveguides. The purpose of this section is not to specify test methods applicable to any particular product or system, but to provide a general basis for all interested product committees. For radiated emission tests, the product committee should refer to the International Special Committee on Radio Interference (CISPR) standards to select emission limits and test methods. For the radiated immunity test, the product committee is responsible for selecting the appropriate test method and immunity limit for the equipment within its jurisdiction. The test methods described in this section are independent of GB/T 17626.3.
