Ok, I understand! Also I have to configure a rx_gain of 60 dB, and a tx_gain of 10 dB If I want to reconstruct the transmitted signal to the very same power level I received it.
The scheme would be: ~~~ signal_generator (QPSK at -60 dBm) -> cable(0.3 dB attenuation) -> rx_usrp -> tx_usrp -> cable(0.3 dB attenuation) -> Signal analyzer (I want to obtain original power here, -60 dBm). *Is it normal that I have to apply roughly 70 dB of gain to replicate the incoming signal?* @Karan, did this happen to you? Appreciate all the help, guys Regards, Brais.
