[Discuss-gnuradio] data size of the usrp source

[sunflower]

I am a beginner of USRP and Python.

 

I have a lot of questions on my new USRP board.

1) How to define the size of data stream from the usrp.source? For example: I want 1024 samples per second or per scope_sink display. How to define the data size from usrp.source?

2) How to define the time and voltage (X and Y) scale in make_scope_sink_f() method

3) Can it implement GPS pulse-per-second (PPS) trigger? Run the receiver program every second synchronize to the GPS PPS pulse.

4) Why the make_scope_sink_c() doesn't work in my machine? It says no oscope_sink_c method

5) Which method can implement auto- or cross- correlation functions?

 

Thanks.
