Hi, all!
Now I'm using USRP1 and RFX2400 d'board. In our project, we have to be able
to reduce transmit power down to -40dBm. Please correct me if my approach is
wrong.
If we set tx_pga=0dB, the transmit power only depends on the level of
signal. So, +/-32767 can give us maximum transmit power 17dBm because the
maximum transmit power of RFX2400 is 17dBm.
Since the power is a square of signal level, we can get -40dBm if we choose
signal level +/-45 roughly.
Am I right?
