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?
