A
Segment
contains
one
or
more
Components,
all
of
the
same
length,
combined
by
means
of
the
elementary
Add,
Subtract,
Multiply,
Divide
operations.

A
Component
is
the
basic
element
for
the
construction
of
a
Segment.
Each
Component
may
be
represented
by
a
standard
waveform
(DC
Level,
Sine,
Cosine,
Exponential,
Triangle,
Rectangle,
Ramp,
Pulse,
Sync,
Sawtooth,
Sweep),
by
a
Formula,
or
its
component
samples
can
be
loaded
from
a
text
file.
In
any
case,
the
samples
of
a
Component
are
calculated/loaded
as
a
function
of
the
ArbStudio
frequency
(sample
rate)
and
of
the
length
of
the
component
itself
(number
of
points).

Edit
waveforms
generated
by
ArbStudio
using
the
Waveform
Editor
tool.
Depending
on
Arbitrary
or
DDS
project
type
mode,
edited
waveforms
acquire
different
meanings.
•
Arbitrary
‐
Edited
waveforms
can
be
generated
as
they
have
been
set.
edited
waveforms
represent
the
signal
carriers
in
case
of
amplitude
modulation.
•
DDS
‐
Edited
waveforms
may
only
represent
a
period
of
the
signal
carrier.
Think
of
a
waveform
as
a
list
of
segments,
where
each
segment
can
be
positioned
any
way
within
the
list
and
repeated
as
necessary.
Consider
the
following
when
selecting
detailed
analysis.
•
Each
waveform
may
be
constituted
by
an
arbitrary
number
of
segments
and
each
segment
can
be
repeated
an
arbitrary
number
of
times.
•
The
maximum
number
of
samples
for
all
waveforms
is
fixed
in
Arbitrary
Mode
(2.097.152
samples
2M
option).
In
DDS
mode,
the
maximum
number
is
2048
samples.
•
Each
waveform
must
be
constituted
by
an
even
number
of
samples
≥
8.
Each
segment
may
have
an
even
or
an
odd
number
of
samples.
•
In
Arbitrary
mode
an
arbitrary
number
of
waveforms
can
exist.
Unlike
DDS
mode,
Arbitrary
allows
the
number
of
edited
waveforms
samples
be
lower
than
the
maximum
number
set
by
the
memory
installed
in
the
instrument.
