Inter-channel Analog Summing:
Waveform Summing sums the waveform from any channel into the next channel.
Alternatively any number of channels may be summed with the signal at the SUM input socket.

Inter-channel Synchronisation:
Two or more channels may be synchronised together. Each synchronised channel may be
assigned a phase angle relative to the other synchronised channels. Arbitrary waveforms and
waveform sequences may be synchronised but certain constraints apply to waveform lengths and
clock frequency ratios. With one channel assigned as the Master and other channels as Slaves a
frequency change on the master will be repeated on each slave thus allowing multi−phase
waveforms at the same frequency to be easily generated.
Channels may be clocked using the master channel, the System Clock or an External Arb Clock.

All waveforms:
The signals from the REF IN/OUT socket and the SYNC OUT socket can be used to synchronise
two instruments where more than 4 channels are required.
Inter-channel Triggering:
Any channel can be triggered by the previous or next channel.
The previous/next connections can be used to 'daisy chain' a trigger signal from a 'start' channel,
through a number of channels in the 'chain' to an 'end' channel. Each channel receives the trigger
out signal from the previous (or next) channel, and drives its selected trigger out to the next (or
previous) channel. The 'end' channel trigger out can be set up to drive the 'start' channel, closing
the loop.
In this way, complex and versatile inter−channel trigger schemes may be set up. Each channel
can have its trigger out and its output waveform set up independently. Trigger out may be selected
from Waveform End, Position Markers, Sequence Sync or Burst Done.
