Hi all,
As far as I know the maximum sampling rate for USRP N210 is 25M sps. To
receive signal with high frequency, such as 300 MHz to 2.2 GH, the RF front
end converts the RF into IF, so the ADC can sample the IF signal. My
question is what the IF value is for daughter-board WBX? Where can I

as shown in the attachment. How can I handle this?

Hi all,
I met a werid problem when receiving. When I ran 'rx_samples_to_file'
example to receive signal from a signal source, e.g. radio station, on two
USRPN210s, the amplitude of received signals are different, seen from
gnuplot.
Does anyone know why this happenes? I guess this is the problem o
Hi Vivian,
Sorry for the delay.
I cannot see anything probelm from your grc graphs. It looks like you have
already received signals from the transmitter. My suggestion is to check
the parameters of packet decoder, GMSK demod, gain, etc. Hope you can sovle
it.

Jamie

flow graph is like:
Wav file source --> Package Encoder --> GMSK Mod --> UHD sink.
--> Audio sink
Do you know what is the problem?

Any ideas?

Hi all,
I am currently working on tranmiting and receiving data using 2 USRPN210s.
I got some ideas from here and did this task using GMSK in GRC.
The transmit side: File source --> Packet encoder --> GMSK Mod --> UHD sink.
The receiver side: UHD source --> GMSK Demod --> Packet decoder --> File
Hi all,
Does anyone know how to record the exact arrival time of a package or the
end of some samples using USRP? I used the following code in GRC:
if __name__ == '__main__':
parser = OptionParser(option_class=eng_option, usage="%prog: [options]")
(options, args) = parser.parse_args()
tb = flow_g
