Re: [Discuss-gnuradio] wrong dB

[GNUBeginner]

Dear Marcus,

If I may, I would like to ask for your guidance please. I have been
experimenting with gr-scan via command line and QSpectrumAnalyzer GUI.  

After injecting -15 dBm signal with 20 dB attenuator at 2412 MHz WiFi
channel to the HackRF One, somehow I am seeing -53 dB peak power with
gr-scan and -51 dB peak power with QSpectrumAnalyzer GUI.  

I am not sure what these values are. This has to be a calibration issue.
Could you please help me understand what these values are?  

Thanks
