两者中取其较小者,所以NFC的允许的调制带宽限值为13,553MHz到13,567MHz。 4) Transmitter spurious and out-of-band emissions(辐射杂散及其带外骚扰) 测试分为两种方法,一种是传导测试方法,另外一种是空间辐射测试方法。传导测试方法仅适用于第三类产品。所以并不适合手机的NFC功能测试,而空间辐射方法适用于任何...
3)Receiver spurious emissions(接收机杂散骚扰) 杂散是指从天线、机箱和接收机辐射出的骚扰。这项测试不适用于接收机同一个在3米内永远处于持续发射状态的发射机相连的这种情况。因为若如此那么测试将会和处于工作状态的发射机一起进行,而这种情况其实已经在前面即发射机的杂散已经测试过了,所以无需重复测试。 接收机...

3)Receiver spurious emissions(接收機雜散騷擾) 雜散是指從天線、機箱和接收機輻射出的騷擾。這項測試不適用於接收機同一個在3米內永遠處於持續發射狀態的發射機相連的這種情況。因爲若如此那麽測試將會和處於工作狀態的發射機一起進行,而這種情況其實已經在前面即發射機的雜散已經測試過了,所以無需重複測試。 接收...

conducted (Part 15.207) and radiated (Part 15.209) limits that are not in the restricted bands. Is this a correct interpretation? For example: For the consecutive bands of 13.36MHz to 13.41MHz and 16.42MHz to 16.423MHz that the spurious emissions are permitted, there is a band of ...
(3) The limits on the field strength of the spurious emissions in the above table are based on the fundamental frequency of the intentional radiator. Spurious emissions shall be attenuated to the average (or, alternatively, CISPR quasi-peak) limits shown in this table or to the general limits...
