Re: [Discuss-gnuradio] TX/RX with USRPN200 and GNURadio

[Carlos Alberto Ruiz Naranjo]

Ok!!

I have Ubuntu 12.04 in this PC http://www.amazon.com/HP-FF825AV-Workstation-2-8GHz-nVidia/dp/B00B90WIGE (Quad Core and 12GB RAM).

With the scheme with loop I have:

Generating: "/home/caruiz_ext/Escritorio/generadoresGNU/top_block.py"

Generating: "/home/caruiz_ext/Escritorio/generadoresGNU/top_block.py"

Executing: "/home/caruiz_ext/Escritorio/generadoresGNU/top_block.py"

linux; GNU C++ version 4.6.3; Boost_105300; UHD_003.006.002-64-g92b0b7ab

-- Opening a USRP2/N-Series device...
-- Current recv frame size: 1472 bytes
-- Current send frame size: 1472 bytes
Using Volk machine: sse4_2_64
UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

What is the problem?

Ruben is absolutely right! In loopback configuration with devices as
sensitive as the WBX, always use an attenuator. Also, in direct
loopback, you really shouldn't need the RX gain, and only risk
damaging the daughterboard and in the worst case your USRP's ADC by
generating too much power.
