I received few days ago my new URSP2 with the WBX daugtherboard and i
First there is two input: one labeled Tx/Rx and the other Rx2. Why is
two Rx input and which one i have to use for reception ?
Second, for my first test i plotted the spectrum of received signal
any antenna) by using the usrp2_ftt.py example script. Looking at the
spectrum shape it appears there is a passband filter of about 8MHz
somewhere in the reception chain. I believed, according to datasheet,
the bandwidth was 30 MHz. An explanation ?
Third, the same spectrum shows lot of spurious harmonics relatively
(compared to the noise floor). Is it normal ?
Thanks in advance for your answers.
