DAC configuration of gr-sounder

GNU Radio
1

Hi Johnathan,

I’m trying to understand the project gr-sounder and have some questions
on that.

  1. What’s the configuration of AD9862 for the transmitter in gr-sounder.
    I didn’t any code setting the register of AD9862 in the python code of
    gr-sounder project.

  2. I used an oscilloscope to watch the signal the gr-sounder transmitter
    sends from the antenna A, but the waveform is like eye diagram and
    contains lots of noise. The frequency of the waveform is not the one
    which I set when run the project. Is there any problem on the method I
    did the test of the project?

Thanks in advance.
