Theres some questions that have been puzzling me,
when i used the usrp_oscope , there are 2 signals one for channel 1, and one
for channel 2; do they resemble the Tx/Rx and Rx ? if so why when i place an
antenna on one of them there's no difference in the signlas?Is there a way i
can isolate the
Hey ,
the best starting point is the tutorials at the link:
http://www.nd.edu/~jnl/sdr/docs/tutorials/
for test the daughter board , use the examples in the usrp directory use the
usrp_scope and usrp_siggen
you can send a signal and receive it this way . About adjusting the PGA use
"src.set_pga
>From the examples ive seen in hier/networking the data coming from the UDP
source seems to be float , is this true? Or is the data format optional ?
Can I receive UDP from 2 different ports simultaneously ?
thanks in advance

hey Justin ,
I havent tried working with the basic daughter boards , but heres a simple
way to transmit a single tone sinusoidal and receive it on a scope , use
usrp_siggen.py and usrp_oscope.py
hope that helps.

im still new to python , i just found that the class usrp.source_c needs some

hey every1 im still new to python,
can some1 tell me what does the module "OptionParser"
and what does "parser = OptionParser(option_class=eng_option)
parser.add_option" mean? is there a command to view the module?
thanks alot for your time

hey kevin,
I too am new to gnuradio but ive started learning few things and even start
running examples on the usrp and soon i will do my own model, now concerning
ur question ,theres actually no program called gnuradio , its just a signal
processing package , all you have to do is write or run
I mean i have data from 2 pins on a DSP at a rate of 4MBps and i wanted to
use Cypress CY7C68013 chip to do a USB interface between those pins and the
computer and make the USRP read that data and send it real time.

I want to use the header pins J101 and J24 (on a RFX2400)to transmit and
receive serial data , Will i need to adjust the verilog codes to assign
those pins ? and would the SPI help in anyway?
I dont need to make any proceesing on that data only DDC/DUC and Rf stages.
Can some1 give me some guide
what about the RFX2400? and can you tell me which pin & will i need to
reprogram the verilog code on the FPGA?
thanks

Hey everyone ,
I was thinking of of giving my USRP data from an external source, Can that
be done using the external pins on the daughter board(RFX2400)?
Will I have to reprogram the verilog code and if so which files should I be
looking at ?
thanks alot for your time

Can some1 tell me what are the PCM input/ouput device names (like hw) for

hey Mochara,
What do you mean by incomplete ,is it cuz you see the pdf as if its cut from
the right side, if this is the case well all schematics are like this
.otherwise i think its a problem from ur pdf viewer or from the copy of the
schematics
cheers

Dear all,
there has been a list of questions that have been puzzling me
1) Can we access the memory of the FPGA on the usrp and store on it data? If
yes does that mean that i can use the usrp without having to connect it to a
PC?
2) what are those pins on the USRP (can they be used to connect
