<P>用示波器测好了</P>

好像有一种TDR的，还有一个是FFT逆变换

<P>when span=0,Spectrum Analyzer can be used as an oscillograph.</P><P>TDR(Time Domain Reflectometer) is a kind of Impedence measurement instrument in time domain.</P><P>The Inverse FFT you mentioned is a function used by VNA.You can use FFT method to transfom the signal in frequency domain to time domain.so you can use VNA as a TDR instrument.</P>[br]<p align=right><font color=red>+5 RD币</font></p>

<P>楼上的，谢谢了！我想问一下，频谱分析仪在分析频域信号时，OSC应该是一个扫频信号，我想问的是它的步进频率是多少，和RBW什么关系？</P>
