Re: [Discuss-gnuradio] dB or dBm

[GNUBeginner]

Thank you for your detailed message. Please correct me if I am on the wrong
path.

I am injecting 802.11g signal using Vector Signal Generator at different
power levels (0 dBm, -5 dBm, -10 dBm, -15 dBm and -20 dBm) using 20 dB
attenuator. After running gr-scan with RF gain 0 dB option at the first
center frequency for this OFDM signal which is 2412 MHz, I am seeing the
following dB results respectively:

-49.37 dB
-49.54 dB
-50.23 dB
-53.58 dB
-58.52 dB

I am also planning to continue the same experiment using the other two
center frequency options which are 2437 MHz and 2462 MHz.

I would appreciate if you could please tell me what I am doing wrong. I am
using modified gr-scan code which has the RF Gain option included by zelfie.

Thanks
