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. |
