.. 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.
