Hello,
I am using the USRP Source block (set number of input channels to 2) to sense two signals, both at 250 MHz. I have gnuradio companion on Ubuntu 16.04 OS on my laptop. I am using the UHD source block and using two channels.
Now,
(1) I need to plot CNO vs time, or Signal voltage vs time on each of the channels (pots RxA and RxB on the B210) at 1 sample per second (I want to keep it variable). The plots need to be generated in real-time.
(2) I need to log the data generated in step (1) in ASCII format in a single file. The file should have the columns 'time', 'CNO (or signal voltage) on Channel 1' and 'CNO (or signal voltage) on Channel 2'.
How can I achieve these using GNU radio companion on Ubuntu 16.04 LTS? Please help.
Regards,
Bidyut
