[Discuss-gnuradio] dB or dBm

[GNUBeginner]

Hello Everybody,

Could anyone please try to explain to me why I am seeing dB values instead
of dBm in the spectrum analyzer GUIs such as QSpectrumAnalyzer or spectrum
scan programs such as gr-scan or hackrf_sweep. 

Because when I inject a signal with -15 dBm power using 20 dB attenuator (no
loss - just a short cable from the Vector Signal Generator to the HackRF
One) to the HackRF One, somehow I see -53 dB as peak power.

Thanks
