频率范围：LED氛围灯的工作频率通常在30 MHz至1 GHz之间，FCC对这个频段内的辐射发射进行了严格限制。发射强度：设备在规定的频率范围内的辐射发射强度必须低于规定的限值。具体限值可参考FCC Part 15.109规定。传导发射限制（Conducted Emissions Limits）：频率范围：传导发射的测试频率范围为150 kHz至30 MHz。发射强...
如果EUT的信号可以有一个及以上的调制方案,则其每一个调制方案和调制参数都必需进行设置及测试,并且它工作的最大和最小的频率都应分别测试出并且记录。 2) Limits for transmitters in the range from 9 kHz to 30 MHz(在频率范围为9 kHz到 30 MHz的发射机限值) 这项测试有两项内容。一项是最大辐射场强度...
传导发射(Conducted Emissions)适用标准:FCC Part 15 Subpart B:检查设备通过电源线等导体传输的电磁干扰信号,确保其符合FCC的标准要求。 抗干扰能力(Immunity Testing)不是强制项目,如果测试参考IEC 61000系列标准进行:虽然这项测试在FCC认证中不是强制性的,但设备通常也会进行测试以确保其在受到外界电磁干扰时仍能正...
FCC SDOC辐射测试限值要求 §15.109 Radiated emission limits. (a) Except for Class A digital devices, the field strength of radiated emissions from unintentional radiators at a distance of 3 meters shall not exceed the following values: 除A类数字设备外,3米距离的无意散热器辐射辐射的场强度不得超过...
1. Conducted Emission(传导骚扰) 测试限值: 注1、在0.15MHz~0.5MHz频率范围内,限值随频率的对数增加而线性减少。 2、如果用准峰值检波器测得的值不大于用平均值测量所规定的限值,则认为用平均值检波器测量也能满足限值的要求。 测试设置如下图所示: ...

測試項目如下表: 1. Conducted Emission(傳導騷擾) 測試限值: 注1、在0.15MHz~0.5MHz頻率範圍內,限值隨頻率的對數增加而線性減少。 2、如果用準峰值檢波器測得的值不大於用平均值測量所規定的限值,則認爲用平均值檢波器測量也能滿足限值的要求。 測試設置如下圖所示: ...
Since conducted emissions testing is usually done to insure that your equipment will comply with the limits of FCC Part 15 or EN55022, the test methods used should conform to the specifications of these two agencies. You will need the following equipment: 1. Shielded room, to allow measurement...
