Hello All,


I have just started learning SDR and new to USRP as well for GNU radio.

SInce i am just a beginner, so i started with very basic examples benchmark_tx.py and benchmark_rx.py on USRP1.

I am using daughter board WBX.


I am getting an overflow problem both for receiver and uhd_fft as well. I tried to search on google but there was no clue for USRP1.

Please help me out to this very initial example problems.


Thank you, in advance.

Below is the command i am passing for tx and rx

benchmark_tx.py -a serial=49270a48 -f 2.2G -m gmsk -r 240 --tx-gain=20 --tx-amplitude=0.8


in another terminal for benchmark_rx i am passing this
benchmark_rx.py -a serial=4d05ac4b -f 2.2G -m gmsk -r 240 --rx-gain=20

forrx and alsofor uhd_fft it is printing the same oooooooo continues.

Thank you.

I wouldn't call the benchmark examples the "very basic." You still need to understand and calibrate a lot of your system before you can get it to work. If you're new, you should start with our tutorials:

These will explain a lot of what you'll be dealing with when you get to this advanced stuff.
