Analog I/O
The
Analog
I/O
page
provides
options
for
configuring
the
DAC
outputs
and
analog
inputs.

Description
Enable Analog I/O —
Enables/Disables
analog
I/O.
DAC Channel —
Selects
the
DAC
channel
to
configure
and
enable.
All
settings
listed
on
the
page
pertain
to
the
selected
DAC.
There
are
5
DAC
channels,
labeled
“DAC0”
–
“DAC4”.
Equation —
Allows
a
user
to
enter
an
equation
that
is
processed
by
the
receiver.
The
equation
can
be
as
basic
as
a
voltage
output
or
as
complex
as
the
functions
and
controls
allow.
Measurement
results
can
be
included
in
the
equation,
as
well
as
the
readings
from
ADC
0
&
1.
Note:
The
result
of
the
equation
is
scaled
according
to
the
minimum
and
maximum
value
and
voltage
settings.
The
DAC
is
programmed
with
the
resulting
voltage
level.
Note:
Update
rate
of
the
analog
I/O
is
based
on
the
measurement
cfg
(frequency
selector).
The
DACs
are
updated
after
a
measurement
set
is
available
and
the
result
of
the
equation
is
ready.
