Default PSD on a spectrum analyzer.

Hello,
I think what we read on a spectrum analyzer is dBm for the specified
range.

dBm/MHz is the PSD.

Lets say if the signal bandwidth is occupying 500Mhz (UWB) and has a
PSD of -30dBm, then what is my power in the entire channel?

(-30dBm)*500 = (1microW)*500 = 500 microWatts = -3dBm

So do I see the -3dBm signal level on the spectrum analyzer in the
whole bandwidth?

Please correct me if I am wrong.


Thanks.
