[USRP-users] GPIO Connector on B205mini

2017-07-27 Thread Thomas Teisberg via USRP-users
Does anyone use the GPIO connector on the B205mini? If so, what cable do you use to access the pins? The crimp contacts for the connector are quite small and the crimping tool is prohibitively expensive, so I've found it difficult to make my own cable. I can't find any off the shelf cables out ther

Thanks Marcus and Philip. I followed Philip's guide and got much further with the build than before, but I'm still encountering an error when running 'bitbake gnuradio-dev-image' (and for reference, I'm sticking with running 'export MACHINE="ettus-e3xx-sg1"' as in the previous guide). The error is

[USRP-users] Determining if an X300 is connected via 10 GigE or 1 GigE

2017-07-27 Thread Perelman, Nathan via USRP-users

Hello Christian, Your configuration of the LO sharing is all reasonable. You are not using timed commands so you will not get repeatable phase offsets between the channels due to the DDC's CORDIC and the RX frontend's IF downconverter not being synchronously reset. The call to set_rx_freq for each

Hi Julian, Thanks a lot for your explanation and I would agree with you, though I am more digital than analog guy. One more piece of information: The signal variations at the beginning of each burst in my tone signal case is actually some DC offset whose level goes down gradually. It lasts abou
