vector_source_X min/max value for the USRP

Hello,

What are the minimum and maximum values for the data when we use the

gr_vector_source_X that will send its data to the USRP. I do not find
this information in the Doxygen documentation.

Because I do not want to crash my USRP with values that will be out the
range.

Another question, when you specify a signal source with a type, we

have to specify the sample rate. But with the vector_source, what is

the sample rate? In the arguments function, there are only the data

and the repeat…

And the amplitude for the signal source, which unity is it? I see the
different example and the value are 16e3 for a sine wave (in example). I
see different values with the usrp_oscope.py program but there is signal
lose. Is it in uV?

Thanks

Julian
