They serve as a constant multiplier of the signal. They are not directly tied to a calibrated power level. As part of the work on the USRP2, there has been some discussion of a normalized power level / signal level going to/from the USRP2, measured at some not yet determined reference point in the system. There would need to be a framework that knew about the various daughterboards, etc. > Also, when the other GNUradio nodes receive the packet, how do I > measure the receive power or the relative receiving amplitude? There are several ways you could do this. Average magnitude squared is one way.
