The baseband signal is simply mixed with the LO in the hardware.

Hello, all.  When I connect a GRC "Fast Noise Source" block output to the input of a "UHD: USRP Sink" (an Ettus E310) and connect a spectrum analyzer to the Tx port on the E310 I can see the RF output.  My question (using either a gaussian or normal distribution specified as a baseband input to the E310), what is the type of modulation being imposed by the E310 to produce the RF output?  Thanks for your time and comment.  Sincerely,
