请问各位前辈，什么叫接收机的窄带响应？该怎么 .. 52e>f5m.

是不是“窄带接收机中快速自动增益控制响应”？

If during the test the immunity RF test signal (see clauses 9.2 and 9.5) causes non-compliance of the receiver with the 2HX/@ERhmu  
specified performance criteria (see clause 6), it is necessary to establish whether this non-compliance is due to a narrow LEb$Fd  
band response or a wideband phenomenon. Therefore, the frequency of the test signal is increased by an amount equal >)>f~>  
to twice the nominal 6 dB bandwidth of the IF filter immediately preceding the demodulator of the receiver, or if $y(;"hy  
appropriate, the bandwidth over which the apparatus is intended to operate, as declared by the manufacturer. The test is -F5BJk  
repeated with the frequency of the test signal decreased by the same amount. 6(n0{A  
If the receiver is then in either or both frequency offset cases in compliance with the specified performance criteria, the b8mH.g&l  
response is considered as a narrow band response. ,06Sm]4L,

上面那段英文怎么理解？？看得好费劲啊！！ Rh>B# \  
请前辈指导。谢谢！！

这段话的意思是说，当测试过程出现不符合标准限值的现象时，首先要判断这种现象是属于宽带响应还是窄带响应，窄带响应不予判定，宽带响应才判为不符合。标准的测试方法里边很介绍得详细。
