output.
When
channel
1
and
2
are
configured
as
Arbitrary
Waveform
Generators,
the
16
‐
bit
digital
representation
of
the
analog
waveform
of
channel
1
is
available
on
DP[0..7]
and
DP[9..16]
of
Pod
A
if
Channel
1
Digital
Pattern
on
Pod
A
is
enabled.
See
Setup
Device,
page
42.
When
channel
3
and
4
are
configured
as
Arbitrary
Waveform
Generators
(ArbStudio
1102/1104
only),
the
16
‐
bit
digital
representation
of
the
analog
waveform
of
channel
3
is
available
on
DP[0..7]
and
DP[9..16]
of
Pod
B
if
Channel
3
Digital
Pattern
on
Pod
B
is
enabled.
The
bit
assignment
to
Pod
Channel
is:
DP[0..7]
≤
SampleBit[0..7]
DP[9..16]
≤
SampleBit[8..15]
DP[8]
and
DP[16]
are
not
significant.

trigger
out
signal
combination
of
CH1
and
CH2
is
sent
to
