这个都写在标准中,你去看EMC标准的definition都会有,每个标准还不一样,有些定义为Class A,B,C,D 比如谐波。一般你说的就是像EN55022定义的Class A工业级和Class B民用级。这些在EN55022的definition里面都有。标准永远是针对测试的,指令是针对法规的。! z, a' v/ X2 y( a) r1 \7 [

CE EN 55022 的 Class A  與 Class B 在法規中有定義& _9 x0 U5 I, |1 a/ |" j

何謂 Digital Device?
& b# H+ r8 j" Y9 `! \8 xFCC 15.3(k)  Digital device.   (Previously defined as a computing device).  An unintentional radiator (device or system) that generates and uses timing signals or pulses at a rate in excess of 9,000 pulses (cycles) per second and uses digital techniques;  inclusive of telephone equipment that uses digital techniques or any device or system that generates and uses radio frequency energy for the purpose of performing data processing functions, such as electronic computations, operations, transformations, recording, filing, sorting, storage, retrieval, or transfer.  A radio frequency device that is specifically subject to an emanation requirement in any other FCC Rule Part or an intentional radiator subject to Subpart C of this Part that contains a digital device is not subject to the standards for digital devices, provided the digital device is used only to enable operation of the radio frequency device and the digital device does not control additional functions or capabilities.  Note:  Computer terminals and peripherals that are intended to be connected to a computer are digital devices.

各位再看看 FCC 15.107 & FCC 15.109 的 limit 是寫- Z/ N. v4 {) l/ C0 w
(a)  Except for Class A digital devices, .......1 d6 x- H. }4 G# e/ M3 f
(b)  For a Class A digital device......3 D, }0 u4 P) ]
" I( \# Z  r( Z' D8 E
因此 除了 ITE 類有分 Class A 與 Class B 外, 其他均應使用 Class B limit.
