Hello, I'm new with USRP, so probably this is a very stupid question. My problem is that I'm trying to transmit a modulated signal through a RFX2400 and receive this signal with this same transceiver so I can test the blocks in GNU Radio Companion work as I expect. I've got two antennas separated by 1m.
The problem is I don't know how to control the emitted power not to burn the usrp. I've got a FFT diagram, but acording to what I've read, the power displayed there is not exactly what i'm transmitting. I also have a amplitud gain control, so I guess that if I put that to the minimum I will transmit enough low power, since I want to transmit less than 0dBm.
Is there any way to control the exact dBm being transmitted apart from using a external device to measure the power?
Thank you

Are you using LabVIEW?

No, I'm just using GNU Radio and the USRP
