[Discuss-gnuradio] uhd digital-bert script !

[saketh kumar]

Hello everyone

   I am working on USRPN200 with RFX2400. I am trying to make digital-bert scripts to work for uhd devices. I have modified them a bit but i am getting some errors which am unable to debug. If anyone can help me out. Attached are my benchmark_tx and transmit_path scripts.

while running the script, it shows me :

address@hidden:~/gnuradio/gnuradio-examples/python/digital-bert$ ./uhd_benchmark_tx.py -f 2500M -g 16
