* :attr:`frequency0`, :attr:`frequency1`, :attr:`frequency2`: in units
of Hz
.. note:: The latencies (pipeline depths) of the nine data channels (i.e.
all except :attr:`config`) are matched. Equivalent channels (e.g.
:attr:`phase1` and :attr:`phase2`) are exactly matched. Channels of
different type or functionality (e.g. :attr:`offset` vs
:attr:`amplitude1`, DDS vs DUC, :attr:`phase0` vs :attr:`phase1`) are
only matched to within one coarse RTIO cycle.
:param channel_base: RTIO channel number of the first channel (amplitude).
The configuration channel and frequency/phase/amplitude channels are
then assumed to be successive channels.
