Dual Arbitrary Waveform Generator
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 remote interface or generate a waveform using one of the ARB modulation
formats. For information on downloading waveforms via remote interface, see the Programming Guide.
The following procedure describes how to create waveform segments using internally generated two tone
and multitone waveforms. In this example, you generate two waveform segments, then name and store them
in ARB memory. After the two waveform segments are named and stored in ARB memory, they are used to
build a waveform sequence in the procedure, “Building and Storing a Waveform Sequence” on page 101.
Generating the First Waveform
1. Press
Preset.
2. Press
Mode > Two Tone.
3. Press
Alignment Left Cent Right to Right.
4. Press
Two Tone Off On to On.
5. Press
Two Tone Off On to Off.
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, as you will see in the next section. The Two
Tone mode was turned off after generation because a waveform cannot be renamed as a segment while it
is in use.
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.
Creating the First Waveform Segment
1. Press
Mode > Dual ARB.
2. Press
Waveform Segments.
3. Press
Load Store to Store.
4. Highlight the default segment AUTOGEN_WAVEFORM.
5. Press
More (1 of 2) > Rename Segment > Editing Keys > Clear Text.
6. Enter a file name (for example, TTONE) using the alpha keys and the numeric keypad, and press
Enter.
The waveform segment is renamed and remains in volatile memory as a WFM1 file.
