Varying signal with usrp_rx_cfile


I’m trying to save a signal to a file coming from a signal generator.
The logical starting point is to use the program After
I put in the center frequency, I would like to vary the signal to view
how it changes with time (via Matlab) but no matter how many samples or
throttling I do, the signal never changes. The frequency that repeats
over the number of samples is the initial one I start with. Is there a
way to make this work? It seems very simple, maybe I’m missing
