Hi Josh and List,
In the data-sheet of the MAX2829 circuit two receiver gains are specified
"Receiver Front-End Gain-Control Settings" and "Receiver Baseband VGA Gain
Settings". From the UHD API we only have one gain parameter. I have been
searching in the UHD code to find where (and how) the s
Hello,
I'm trying to implement the calculation of phase delay using a routine of
direction finding. I have two daugtherboards lfrx in a USRP at 25MHz and I
intend to put the subdevice rxab in order to receive a stream complex in
each daugtherboards. In each of daugtherboard will be placed an

That's exactly what I did in my semi-permanent GPS-disciplined oscillator

Hi all,
At the request of several users, CGRAN now keeps track of project statistics
through SVN logging. This keeps track of checkouts and updates, on a
per-project basis. So if anyone wants statistics for the number of
"downloads" on their project (starting as of today), you can email me

Hi All,
How often is PPS sampled? I guess the answer is that the USRP2 runs at

Hi,
Probably a stupid question...
By connecting the BURX's 26MHz clock to the USRP2's 100MHz ref. input, as
described in the source, does this pull the mainboard clock to 26MHz, or does
it
just phase lock to it? i.e. if I collect samples with usrp2_rx_cfile, these
will
all be samples at 26MHz

Thanks, so it is.
Unfortunately though, I have discovered that the gain for an RFX card cannot be
adjusted (min=0, max=0, step=0), requiring a massive multiply value in
gnuradio-companion, so its all very distorted. :-(
Cheers,
Dave

Hi everyone ,
I was just wondering if we can capture multiple frequency from usrp
simulataneously.If not why is it so.And if we can , can some one tell me if
we need to change the usrp programming part , means fpga programming /c++
programming / or any.
Thanks all for your concern in advance.
