David If the reduced configuration does nothing that might make the EMC situation worse (changes to enclosure apertures, substitution of different cables, etc) then you should not need to do any additional testing, just seek a Notified Body opinion on the changes to the build standard. It is up to you to judge whether it costs less to document the changes and prepare the submission to the NB and whatever the charge is for the NB opinion compared to the costs of just re-testing the product. You may also be able to take a compromise route, where a NB agrees what additional tests may be required to validate the new build standard; e.g. you may repeat radiated emissions tests because you have removed a module and replaced it with a blank panel, but accept conducted emissions tests because you are using the same power supply and have reduced the load, which should reduce the emissions. Consult your test house / Notified Body to discuss the best way forward; most will be happy to offer you comparative costings for different approaches.

The customer has a radio unit, a sub-configuration (extracted components/assemblies, software) of a unit already tested fully to the appropriate R&TTE Directive harmonised standards. Is additional testing required or can the full testing of the maximum configuration cover the sub-configuration unit If we perform partial testing on this sub-configuration to R&TTE harmonised standards, can the customer issue a DoC for the R&TTE Directive or is an R&TTE Notified Body Opinion required. The above question is also applicable to units which are not sub-configurations (customer wants to reduce testing costs). Thanks in advance to anyone who answers.
