问题1 :标准FCC Part15B中B代表什么意思?

答:其实准确的说FCC Part 15 B应该是FCC Part 15 Class B (B级数字装置)。

ClassA和ClassB的定义:

Class A digital device - A级数字装置.

A digital device that is marketed for use in a commercial, industrial or business

environment, exclusive of a device which is marketed for use by the general public or is

intended to be used in the home.投放市场供在商业、工业或商务环境中使用的数字装置,

但不包括投放市场供一般公众或 家庭使用的装置。

Class B digital device - B级数字装置.

Class B digital device. A digital device that is marketed for use in a residential environment

notwithstanding use in commercial, business and industrial environments. Examples of

such devices include, but are not limited to, personal computers, calculators, and similar

electronic devices that are marketed for use by the general public. Note: The responsible

party may also qualify a device intended to be marketed in a commercial, business or

industrial environment as a Class B device, and in fact is encouraged to do so, provided

the device complies with the technical specifications for a Class B digital device. In the

event that a particular type of device has been found to repeatedly cause harmful

interference to radio communications, the Commission may classify such a digital device

as a Class B digital device, regardless of its intended use.投放市场不仅供在商业、工业或

商务环境中使用而且要在居住环境中使用的数宁装置。这类装置的例子包括(但不限于) :

个人计算机、计算器以及其它投放市场供- -般公众使用的类似电子装置。注:职责部门也可

以把投放市场以供商业、工业或商务环境中使用的装置定义为B级装置;事实上FCC也鼓

励这.举措，只要该装置能满足B级装置的技术规范。若某类型装置反复地对无线电通讯

产生有害干扰，则FCC可能会将之归为B级数字装置而不管共用途如何。

问题1:FCC的目录?

答:下面是FCC PART15日录章节内容:

Subpart A- General (一般要求)

Subpart B - Unintentional Radiators (无意辐射体)

Subpart C - Intentional Radiators (有 意辐射体)

Subpart D - Unlicensed Personal Communications Service Devices

Subpart E - Unlicensed National Information Infrastructure Devices

Subpart F - Ultra-Wideband Operation

Subpart G - Access Broadband Over Power Line (Access BPL)

问题3:有意辐射体和无意辐射体的定义

答: Intentional radiator (有 意辐射体)-定 义. A device that intentionally generates and

emits radio frequency energy by radiation or induction.通过辐射或感应的方式有意产生和

发射RF (射频)能量的装置。

注:红外线设备(比如:红外线遥控器)因为红外线不属于RF (射频)， 所以它不属于有

意辐射体。另外，如果红外线设备的clock frequency (时钟频率)小于9KHz,那么它也不

需要FCC Doc测试;如果clock frequency (时钟频率)大于9KHz,那么它需要FCC测

试，必须符合FCC Part 15.209 (Radiated emission limits. -辐射测试)

Unintentional radiator (无意辐射体
