"why pulse is broad band and CW is narrow band? "

To spread a pulse in frequency domain is several frequency,that is pules is made by combining several frequency signals.

To spread a clear CW in frequency domain is only one frequency signal.
That is why pulse is broad band and CW is narrow band.

支持楼上的,pulse是时域上的,在频域上是离散的,所以如果用单一频点去测的话,值是要低的.

is it mean
time domain => boardband => measure with QP,
freq domain => narrow band => measure with peak?

搞不太清楚學習了
