Note that the phase difference between the 2 channels might not be exactly 0.25 turns, but it is a constant.

It can be negated by adjusting the \texttt{phase} parameter.

Similar to the 10 MHz single-tone RF signals, specify \texttt{phase} when calling \texttt{dds.set()} in \texttt{configure\char`_ram\char`_mode}.
|

For example, set phase to 0 for the channels (\texttt{phase=0.0}).
