Electromagnetic compatibility and Radio spectrum Matters (ERM); Radiated measurement methods and general arrangements for test sites up to 100 GHz (V1.1.1)
The present document provides information on general arrangements for radiated measurements from 30 MHz to 100 GHz@ and guidance on the use of radiation test sites. The present document captures the state of the art regarding radiated measurement techniques@ their capabilities and associated arrangements. Whilst it remains the responsibility of the individual technical bodies to define their own test methodologies@ the present document should be considered as a source of what is possible@ practical and therefore recommended. The basic principles of substitution@ pre-substitution and field strength measurements are outlined in the present document. The general descriptions and their calibration and validation are included for Open Area Test Sites (OATS)@ Semi-Anechoic Rooms with conductive ground plane and Fully Anechoic Rooms (FAR). Equipment and its arrangement when used to perform radiated measurements such as the following are addressed: ? Measuring receiver. ? Test antennas. ? RF cables and waveguides. ? External harmonic mixers. The extension to the measurement frequency range necessitates some information to the radiated test methods and their associated expanded measurement uncertainty.
