Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Electromagnetic compatibility a

23、nd Radio spectrum Matters (ERM). Introduction The recent creation of TS 103 051 i.1 came about because of the demand for information and guidance in the frequency range up to 100 GHz. Whilst TS 103 051 i.1 covers the expanded measurement uncertainty associated with measurement activities, it became

24、obvious that a companion document was required that deals with the corresponding methods of measurement. The present document can be considered as complementary to TS 103 051 i.1 and is based on the previous TR 102 273 5 series of documents. It is offered as a practical guide to making radiated meas

25、urements of electromagnetic fields at frequencies up to 100 GHz. In doing so, it has incorporated the state of the art regarding measurement techniques available to test houses and commercial laboratories. From an international perspective, measurements for radio testing, both radio parameters and E

26、MC are already required above 1 GHz, notably in the US FCC regulations (40 GHz, ITU-R spurious emissions (300 GHz) and CISPR EMC testing (6 GHz). These extensions to the measurement frequency range necessitate a review and some level of co-ordination to ensure that a common approach to test methods

27、and their associated measurement uncertainty calculations are agreed. Contrary to the requirement for performing measurements at frequencies up to 100 GHz, the descriptions of traceable validation or the calibration of test sites are weak and lead to larger uncertainties in the measurement results.

28、This document expands the information and makes recommendations for open area test sites, semi-anechoic rooms and anechoic test chambers and their use for making radiated measurements up to 100 GHz. Measuring receivers i.e. test receivers or spectrum analysers with coaxial inputs are commercially av

29、ailable for frequencies up to about 67 GHz. The frequency range can now be extended by the use of external harmonic mixers. These devices use an EHF local oscillator signal derived from the measuring receiver and applied to the mixing element together with the incoming signal under investigation. Th

30、e mixing element internally generates harmonics of the LO that mix with the incoming signal thereby creating an output IF signal that is within the range of the measuring receiver. Such devices are waveguide based and have frequency ranges matching the waveguide bands. The present document is offere

31、d as an assistive document to ETSI standard makers. 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. ETSI ETSI TS 103 052 V1.

32、1.1 (2011-03)61 Scope 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

33、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-subst

34、itution 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 whe

35、n 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 expande

36、d measurement uncertainty. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
