問(wèn)題1 :標(biāo)準(zhǔn)FCC Part15B中B代表什么意思?

答:其實(shí)準(zhǔn)確的說(shuō)FCC Part 15 B應(yīng)該是FCC Part 15 Class B (B級(jí)數(shù)字裝置)。

ClassA和ClassB的定義:

Class A digital device - A級(jí)數(shù)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(chǎng)供在商業(yè)、工業(yè)或商務(wù)環(huán)境中使用的數(shù)字裝置,

但不包括投放市場(chǎng)供一般公眾或 家庭使用的裝置。

Class B digital device - B級(jí)數(shù)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(chǎng)不僅供在商業(yè)、工業(yè)或

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

個(gè)人計(jì)算機(jī)、計(jì)算器以及其它投放市場(chǎng)供- -般公眾使用的類似電子裝置。注:職責(zé)部門(mén)也可

以把投放市場(chǎng)以供商業(yè)、工業(yè)或商務(wù)環(huán)境中使用的裝置定義為B級(jí)裝置;事實(shí)上FCC也鼓

勵(lì)這.舉措，只要該裝置能滿足B級(jí)裝置的技術(shù)規(guī)范。若某類型裝置反復(fù)地對(duì)無(wú)線電通訊

產(chǎn)生有害干擾，則FCC可能會(huì)將之歸為B級(jí)數(shù)字裝置而不管共用途如何。

問(wèn)題1:FCC的目錄?

答:下面是FCC PART15日錄章節(jié)內(nèi)容:

Subpart A- General (一般要求)

Subpart B - Unintentional Radiators (無(wú)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(wèn)題3:有意輻射體和無(wú)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(guò)輻射或感應(yīng)的方式有意產(chǎn)生和

發(fā)射RF (射頻)能量的裝置。

注:紅外線設(shè)備(比如:紅外線遙控器)因?yàn)榧t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(shè)備的clock frequency (時(shí)鐘頻率)小于9KHz,那么它也不

需要FCC Doc測(cè)試;如果clock frequency (時(shí)鐘頻率)大于9KHz,那么它需要FCC測(cè)

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

Unintentional radiator (無(wú)意輻射體
