Is the receiver buffer size in bytes or samples ?

Tom,
that is exactly the conclusion I came to after lots of googleing !.
Thanks a lot for the really good help. I am glad that now guys who
adventure in c++ development will have this piece of info.

Jorge,
Your sample rates do not match. The sample rates your USRP2 is operating
at is fixed for a given decimation/interpolation, and you must choose
sample rates in your upstream and downstream blocks to match.
For instance, in your receiver chain, you are using a decimation rate of
64. This mea

bytes
Its a direct proxy for SO_REVBUF socket option.

Hello,
I tried to print what data gr_vector_sink_f contains in the following code:
#!/usr/bin/env python
import howto
from gnuradio import gr, gru
from gnuradio.gr import firdes
from optparse import OptionParser
from gnuradio import blks2
class howto_square (gr.top_block):

So what you are saying is when I create an instance of the class, only the
data and blocks are initialized and glued together, but the object didn't
run yet. So source will never get to sink unless I use the run() method and
then I can print the data.
Let me know if this if I am correct.

Hi
Is it possible to use USRP as simple Network Analyzer?
We could use RX Part as Spectrum Analyzer and TX Part as Tracking Generator.

Did you ever get this fixed? I'm seeing the same problem...

Just saw this thread now... I'm seeing this problem with my USRP2s and the
WBX board. However, I'm not using UHD. Do you know a fix for this outside
of UHD?
