Block used to stream samples from a USRP device.

To adjust parameters like Center Frequency while running, use QT GUI Range or another control. The input message port called "command" can be used to change frequency, gain, and other parameters via Message Passing.

A common arrangement is to use the QT GUI Frequency Sink's output message port and connect it to the USRP Source's input port, so that when a user double-clicks within the GUI to change frequency, the change gets propagated to the USRP device. See example flowgraph below for how this is connected.
