Description / Abstract:
This annex provides background information for each requirement in the main body of the standard. The information includes rationale for the test requirements and guidance for application of the requirements. This information should help users understand t.he intent behind the test requirements and adapt them in the Electromagnetic Interference Test Procedures (EMITP) as necessary for particular applications. This annex is provided for guidance purposes and, as such, should not be interpreted as providing c-0ntractual requirements.
Structure
This annex follows the same general format as the main body of the standard. A "DISCUSSION'' paragraph is provided for each requirement contained in the standard.
Purpose
This standard establishes general techniques for use in the measurement and determination of the electromagnetic emission and susceptibility characteristics of electronic. electrical, and electromechanical equipment and subsystems.
Application
The testing techniques of this standard are '15ed to obtain data for determination of compliance with the specified EIA/IS-647 requirements. The test methods contained in this document shall be adapted by the testing activity for each application. The adapted test methods should be documented in the Electromagnetic Interference Test Procedures (EMITP) Application Guide recommended by EINIS-647.
Emission and susceptibility designations
The test methods contained in this standard are design_.ated in accordance with an alpha-numeric coding system. Each method is identified by a two letter combination followed by a three digit number. The number is for reference purposes only. The meaning of the individual letters are as follows:
C : Conducted
R = Radiated
E = Emissions
S = Susceptibility
a. Conducted emissions tests are designated by "CE-."
b. Radiated emissions tests are designated by "RE-."
c. Conducted susceptibility tests are designated by "CS- ."
d. Radiated susceptibility test are designated by "RS-.''
e. "-·" = numerical order of test from l 0 l to 199 .
