Hi All,
In dxc_control::set_dxc_freq is the following line:
set_dxc_freq(double dxc_freq){ return d_u->set_rx_freq(d_chan, dxc_freq);
If we go to usrp_standard.h we see that channel is between 0 and 3. I think
for the standard ".rbf" it is 0 or 1 depending on the side (A or B) as I
recall. However, the value of d_chan is passed from the first parameter of
the function usrp_standard::tune. The documentation in usrp_standard.h says
"which DDC channel we're controlling (almost always 0)". If we set this to
zero we will always control the A side and never the B side dxc frequency.
?
BR/
