Hi Kevin, Thanks for the tips! Ya, I know I was wrong somewhere in my flowgraph, I’ve done the tutorials in GNU Radio. May I know roughly which area my flowgraph is wrong?
I want to do a transceiver, so instead of receiving a signal elsewhere out of the board. I self-generate out a chirp signal internally in USRP B210 and do a loopback to the receive port and then re-transmit out
using another transmit port. Thank you in advanced! From: Kevin
McQuiggin [mailto:address@hidden Hi Alvin: Well, for one thing, you are trying to write USRP output samples to a file at 30 MB per second. That is likely to generate overflows. Your flowgraph indicates to me that you haven’t fully internalized how gnuradio works and how it interacts with whatever front-end hardware you are using. Don’t take this comment as overly critical, we all (myself included) started with only basic understanding, and had to build our skills from there. I suggest going to the gnuradio web site and following, as a start, the set of tutorials that have already been recommended by others on the list. They will help you as you start to climb the learning curve! Kevin Sent from my iPhone
