I am very interested in this feature of USRP2.
Would you please inform us what spec. 10MHz
and 1PPS signals are needed? What waveform
are they? What phase relation do yo
Sachin,
I don't know if this is helpful, just sharing my experience.
1. You may want to check tunnel.py, in which there is a CSMA scheme --
Eric told me this a couple of weeks ago.
2. It is possible to do some carrier sensing by ourself. You can just
read the signal from the USRP and compare the
Hi,
As per the current status of GNU Radio, I got to know that there is no MAC
(CSMA) implementation. Therefore I am not sure if I can get the signal from
signal processing blocks of GNU Radio about the carrier sensed by USRP
receiver.
Please help me in this regard.
Till now I am able to locate

The internal clock (a very clean VCXO) is locked to the external
reference. You have a lot

Actually, you can use 100 MHz as well, you will just need to change one
line of the firmware to set the R-divider on the PLL.
You can use any frequency for which the following equation has a solution:
100 MHz / N = Ref / R
for which N and R are integers and smaller than 32K

I'm wondering if it is possible to connect the USRP2 to an external
100MHz clock like the USRP was able to be modified so it could connect
to an external 64MHz clock. I don't see any place to solder on a SMA
connector but there are a set of pins labeled Test CLK. Could that be
used for inputting an
I obtain this plot from 2.23GHz to 2.90GHz (with a Flex2400) but I
don't know how to put the correct frecuency on the x axis.
Because if I put this:
g('set xrange[223000:29]') # I can't see anything!
To plot I have done this:
g = Gnuplot.Gnuplot(debug=1) # Out of the while loop
g
Apologies for the CFP advertisement, but it is relevant to many of us
whose use of GNU radio can be considered as "sensor systems".
