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
Agilent 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.
Figure 3-9 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 sequence, as described on page 93.
1. Generate the first waveform:
a. Press Preset >
Mode > Two To ne > Alignment Left Cent Right to Right.
b. Press
Tw o To n e O f f O n 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.
NOTE Because there can be only one AUTOGEN_WAVEFORM waveform in memory at any given time,
you must rename this file to clear the way for a second waveform.
