Db power value

Added by Roberto Collazos about 12 years ago

Hello,

I've a question from grc, I hope you can help me ...
In the Y axis of the attached picture, it shows a "dB" level, I want to know if this is the real value of the captured signal (dB).
I want to convert it into a power level 'mW' (10^(dBm/10)). I thought it could be dBfs (dB full scale) and I'm not quite sure if it's the absolute power level or dBfs.
Is there any way in the GRC, to show me a numerical value? or I just have to look and compare the plot in Y axis. Any suggestion is welcome.

-Thanks
