Just to add to Tanias comment, all medical electrical equipment is exempt from part 15.

Doug, et al, FCC Part 15 addresses digital devices only. And they continue to use the term "digital" over and over again. The scope of FCC Part 15 does not address analog devices, whether they be industrial, commercial, or medical test equipment. However, the FCC are exempting (and some say temporarily) digital devices that are "used exclusively as industrial, commercial, or medical test equipment." Therefore, no, a company that makes analog test equipment does not have to EMC test such products. (And someone tell me please how exactly they would test them if they wanted to!)

Okay, follow me on this for just a minute. " 47 CFR, 15.103, Exempted devices. (c) A digital device used exclusively as industrial, commercial, or medical test equipment." The important word is "digital". Why just digital? Does this mean if a company makes analog industrial, commercial, or medical test equipment, that equipment MUST be tested?
