Unwanted Emissions – Guidance and methodologies when using typical equipment performance in sharing/compatibility studies


Related WI
Scope a.             To be used by other CEPT / ECC groups when conducting sharing/compatibility studies

b.             To provide clear guidance on the use of the typical performance of equipment in sharing/compatibility studies in addition to limits e.g. those set in ECC Recommendation (02)05, ERC Recommendation 74-01 or European Harmonised Standards.

c.             Further investigate and provide methodologies on the use of typical performance in sharing/compatibility studies. This may include:

i.              Guidance on defining typical performance of the equipment through measurements;

ii.             Defining a methodology for developing the distribution of values for typical performance of equipment, for sharing/compatibility studies, this may include a guidance on determining an ‘average’ level of spurious emissions.

iii.            Defining a methodology to introduce power distribution in sharing/compatibility studies.

iv.            Guidance on use of a sensitivity analysis.

d.             Provide guidance on how the boundary between the Out of Band domain and the Spurious domain based on the 250% rule relates to the discontinuity of typical unwanted emissions in the Out-of-band and Spurious domains.

e.             Look for any baseline assumptions that can be defined for the typical performance of equipment that can be used in sharing/compatibility studies.

f.             Changing limits in ERC Recommendation 74-01 is outside the scope of this work. However, developing an informative annex to 74-01 could be within scope.

g.             Liaise with other SE project teams and ETSI where appropriate.

h.             Use ECC report 249 as a basis for this work. Other work references could include ECC Report 207 and ERC Report 065 which give examples of previous studies where performance better than the limits were used.
