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

OMPONENT
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.
