Re: [Discuss-gnuradio] dB or dBm

[Gilad Beeri (ApolloShield)]

Yes - he meant a constant tone, a simple sinusoidal signal with fixed frequency and amplitude (Acos(wt)).

And you can't measure the power directly. What you can measure is the graph (function) between the injected power (as determined in your signal source) to those strange dB values. After you get to the best function you can get, you conclude power of other signals by comparing those dB values. As said, you need to be aware of the different frequencies and gain values.

Also, how could I measure power? The program is giving some strange dB
values...
