Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility an

24、d Radio spectrum Matters (ERM). Introduction The present document has been produced in response to the need for measurement uncertainty information above 1 GHz, and to determine practical maximum frequency of measurement which is also cost effective for manufacturers self declaration, and for test l

25、aboratories offering certification testing. Considerable work on radio test methods and measurement uncertainty up to 1 GHz has previously been undertaken by ETSI to determine the contributions to the calculation of measurement uncertainty and these have been published in ETSI TR 100 028 1 to 2 and

26、TR 102 273 3 to 10. The changing role of regulation due to the implementation of the Radio and Telecommunications Terminal Equipment (R radiated spurious emissions; and EMC radiated emissions. The maximum frequency recommendations are based upon current capabilities of measurement equipment at May 2

27、003 and the ability to calculate measurement uncertainty from traceable calibration certificates. Frequencies above the recommended maximum frequency for each method of measurement are for further study. A recommendation is given on how to apply the laboratory calculated measurement uncertainty to a

28、 measured parameter and to assess the quality of the measurement against a defined limit given in a standard. The present document contains the results of many discussions held with test equipment manufacturers, test laboratories, administrations, trade associations, societies, and members of the GR

29、SC, all who have an interest in measurement uncertainty above 1 GHz. In determining the maximum acceptable measurement uncertainty, particular account has been taken of current methods of measurement already identified in ETSI standards. However where there is an inconsistency, or uncertainties that

30、 have not previously been taken into account in the uncertainty budgets, these are clearly identified in the relevant clauses. Whilst an analysis has been carried out on safety related measurements by ETSI, the responsibility for standards rests with CENELEC. The present document will include any re

31、commendations from CENELEC TC 106X related to radiated measurements in a future edition. Fixed link microwave methods of measurement do not use radiated measurements only conducted measurements (excepting EMC testing). Therefore they are considered outside the scope of the present document. However,

32、 as new technologies with integral antennas are being developed, this may be reviewed in a future edition. Satellite equipment is outside the scope of the present document, however, this may be reviewed in a future edition. The measurement uncertainty for conducted measurements is outside the scope

33、of the present document. The use of a test jig for radiated RF measurements of integral antenna radio equipment is outside the scope of the present document. Annex A contains historical examples of the application of shared risk within ETSI standards. Annex B contains examples of measurement uncerta

34、inty calculations, some of which are still under development. Annex C is reserved for data files to be used in the calculation of radio parameter measurement uncertainties. Annex D contains a list of all relevant contributions to radiated measurement uncertainty extracted from TR 102 273-1-2 4. ETSI
