Laplace Instruments
Emissions test requirements cover both radiated (air borne) and conducted (down cables).
The many standards which quote these requirements specify the measurement technique and the acceptable limits. The Laplace range of test equipment includes virtually all commercial standards, and many military standards too.
Generally, emissions measurement equipment will include an EMC analyser together with some form of antenna (for radiated) or ‘transducer’ (for conducted) ancillaries
