To­day, in the densely pop­u­lated ur­ban ar­eas of the coun­try, you may not find any space where elec­tronic or elec­tri­cal de­vices are not be­ing used. As each de­vice in­duces an elec­tro­mag­netic field, there is a need for tests related to elec­tro­mag­netic com­pat­i­bil­ity (EMC), elec­tro­mag­netic in­ter­fer­ence (EMI) and field strength, in or­der to iden­tify the de­vice’s field of op­er­a­tion.

All elec­tronic prod­ucts, ir­re­spec­tive of the in­dus­try (mil­i­tary, in­dus­trial, com­mer­cial or res­i­den­tial) they are used in, must func­tion prop­erly even when sub­jected to an elec­tro­mag­netic en­vi­ron­ment. The EMI/EMC tests help to find out the be­hav­iour of these prod­ucts in an elec­tro­mag­netic field. Ad­di­tion­ally, the field strength testers help to iden­tify the strength of the elec­tro­mag­netic field, and are very im­por­tant in­stru­ments in the tele­com space, as well as in the aero­space and mil­i­tary sec­tors.
