This paper presents three different case studies where the electromagnetic emissions of atypical equipment (a photovoltaic system, a passenger boarding bridge and a pallet washing machine) have been assessed in situ using time-domain measurement systems. The magnetic field (150 kHz-30 MHz) and electric field (30 MHz-1 GHz) emissions are considered. The technical challenges encountered and the solutions adopted for each scenario will be highlighted by describing the methodology employed. The goal is to relate the empirical knowledge and know-how gained through those study cases with the specific requirements and procedures defined in the standards. In that sense, multi-channel time-domain emissions measurements have been essential to carry out those measurement campaigns efficiently. The results are summarised as lessons learned during the experiences reported in this article. This work is relevant to support the revision or development of standards about in situ EMC testing as it provides helpful evidence to validate alternative radiated emissions measurement methods under realistic conditions.
