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 272

• “Configuring Tone Powers and Tone Phases” on page 272

• “Removing a Tone” on page 273

• “Generating the Waveform” on page 273

• “Configuring the RF Output” on page 273
