Creating a Custom Multitone Waveform
Creating a Custom Multitone Waveform
Using the
Multitone Setup
table editor, you can define, modify and store user-defined multitone
waveforms. Multitone waveforms are generated by the dual arbitrary waveform generator.
This section teaches you how to perform the following tasks:
•
“Initializing the Multitone Setup Table Editor” on page 366
•
“Configuring Tone Powers and Tone Phases” on page 366
•
•
“Generating the Waveform” on page 367
•
“Configuring the RF Output” on page 367
Initializing the Multitone Setup Table Editor
1. Press

.
You now have a multitone setup with five tones spaced 20 kHz apart. The center tone is placed at the carrier
frequency, while the other four tones are spaced in 20 kHz increments from the center tone.
Configuring Tone Powers and Tone Phases
1. Highlight the value (
