問題1 :標準FCC Part15B中B代表什么意思?

答:其實準確的說FCC Part 15 B應該是FCC Part 15 Class B (B級數字裝置)。

ClassA和ClassB的定義:

Class A digital device - A級數字裝置.

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.投放市場供在商業、工業或商務環境中使用的數字裝置,但不包括投放市場供一般公眾或 家庭使用的裝置。

Class B digital device - B級數字裝置.

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.投放市場不僅供在商業、工業或

商務環境中使用而且要在居住環境中使用的數寧裝置。這類裝置的例子包括(但不限于) :

個人計算機、計算器以及其它投放市場供- -般公眾使用的類似電子裝置。注:職責部門也可

以把投放市場以供商業、工業或商務環境中使用的裝置定義為B級裝置;事實上FCC也鼓

勵這.舉措，只要該裝置能滿足B級裝置的技術規范。若某類型裝置反復地對無線電通訊

產生有害干擾，則FCC可能會將之歸為B級數字裝置而不管共用途如何。

問題1:FCC的目錄?

答:下面是FCC PART15日錄章節內容:

Subpart A- General (一般要求)

Subpart B - Unintentional Radiators (無意輻射體)

Subpart C - Intentional Radiators (有 意輻射體)

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)

問題3:有意輻射體和無意輻射體的定義

答: Intentional radiator (有 意輻射體)-定 義. A device that intentionally generates and

emits radio frequency energy by radiation or induction.通過輻射或感應的方式有意產生和

發射RF (射頻)能量的裝置。

注:紅外線設備(比如:紅外線遙控器)因為紅外線不屬于RF (射頻)， 所以它不屬于有

意輻射體。另外，如果紅外線設備的clock frequency (時鐘頻率)小于9KHz,那么它也不

需要FCC Doc測試;如果clock frequency (時鐘頻率)大于9KHz,那么它需要FCC測

試，必須符合FCC Part 15.209 (Radiated emission limits. -輻射測試)

Unintentional radiator (無意輻射體) - 定義. A device that intentionally generates radio

frequency energy for use within the device, or that sends radio frequency signals by

conduction to associated equipment via connecting wiring, but which is not intended to

emit RF energy by radiation or induction.有意產生射頻能量供給裝置內部使用或通過連線

將射頻信號傳送給有關設備使用,但不是有意輻射或感應的方式來發射射頻能量的任--裝置
