I have two questions on USRP and GNU radio use.
(1) Change of output file of file_sink
I would like to record data into files. I am now using
file_sink in the flow graph. Now my program is very
simple and it can record data into one file only.
I want to change the program that it can start/stop
receiving, and for different runs, record data into
different files. How can I change output file
(= filename)? Do I need to stop the program and
return to OS for each file output?
(2) Set PLL frequency of RFX400
I am using RFX400 for receiving. It works fine.
But I would like to set PLL (the local oscillator
on the board) to a certain frequency. Please show
me how to control frequency of the PLL on the board.
Thank you very much for your help.
