Basic Digital Operation
Using the Dual ARB Waveform Player
Creating Waveform Segments
There are two ways to provide waveform segments for use by the waveform
sequencer. You can either download a waveform via the remote interface, or
generate a waveform using one of the ARB modulation formats. For
information on downloading waveforms via the remote interface, see the
Keysight Signal Generators Programming Guide
.
A waveform sequence is made up of segments but can also contain other
sequences. Any number of segments, up to 32768, can be used to create a
sequence. This limit count is determined by the number of segments in the
waveform sequence. Segments and sequences can be repeated within a
waveform sequence and the total of all segments and repeated segments
cannot exceed the limit count. The following diagram shows a waveform
sequence made up of two sequences and three segments. In this example the
segment count is eleven.

Waveform Sequence Diagram
The following procedure describes how to create two waveform segments,
then name and store them in ARB memory. After you name and store the two
waveform segments in ARB memory, you can use them to build a waveform
.
1.
Generate the first waveform:
a.
Press Preset >
Mode
>
Two Tone
>
Alignment Left Cent Right
to
Right.
b.
Press
Two Tone Off On
to On, then to Off.
You turn off the Two Tone mode after generation because a
waveform cannot be renamed as a segment while it is in use.
This generates a two tone waveform with the tone on the right placed at
the carrier frequency. During waveform generation, the
T–TONE
and
I/Q
annunciators activate. The waveform is stored in volatile memory, with the
default file name
AUTOGEN_WAVEFORM
