Hi Roshan,
With the in-band signaling implementation we have added timestamps to
all data across the USB bus. You can find the new packet structure here:

I'm not sure what kind of application you want to create or u
Hi all,
For one of our applications we think we need timestamps for some or all
samples coming across the USB bus. I know there was some mention of this
a while ago on the list, but I didn't find an open ticket on Trac.
Obviously we would submit our changes back to gnuradio for inclusion in

Thank you Brian and Mande.

You'll need gnuradio header files installed along with QT 4.2 with
development headers. (QT 4.1 should also work, but is untested.)
Fftw3 is also a dependency, but I'm pretty sure that that comes with gnuradio.

G'day,
building current source results in an error due to missing file gr_runtime.i.
It appears runtime.i was renamed to gr_runtime.i which was missed in the
trunk.

Thanks, this has been updated on the trunk.

Here is a patch to add this method to the base class, since this will
produce an error if trying "-A" on a subdev that's not an RFX. - MLD

Anyone know what the allowable gain settings are when using the USRP
with the LFRX daughterboard? I believe I read somewhere that 20 is the
default and units are dB, but what are the min/recommended/max values?

Hello,
I (Sabu) too is getting familiar with USRP in an inevitably slow pace.
Hope the following will answer your question partly.
This URL http://gnuradio.org/trac/wiki/TitleIndex gives important references
that
can be helpful for GNUradio s/w installation depending on your choice of OS.

Did anyone successfully compiled it ? I have many compilation errors.

The maximum (at 16 bits complex samples) data rate across USB on the
USRP is 16 MHz; hence the minimum decimation rate of 4. My understanding
is that this decimation gives more bits -- since you're combining 4
samples together, you can now extrapolate
17 matches
