[Discuss-gnuradio] FFT plot unit

[Gerome Jan L]

I was able to gather results, and I am really confused with it. I generated a -30 dB signal based on the fft plot shown and transmitted it using a usrp. My spectrum analyzer received a signal at -50 dBm (-80 dB) and my receiver which also uses a usrp received the signal and plotted it at -30 dB. My question is, what is the unit of the fft plot? Is it dB or dBm?
