Custom Digital Modulation (Option 431)

Using the Arbitrary Waveform Generator

This section teaches you how to build dual arbitrary (ARB) waveform files containing custom TDMA,

digital modulation for testing component designs.

Figure 11-5 Adding Custom Modulation to a Waveform

Using Predefined Custom TDMA Digital Modulation

This section teaches you how to perform the following tasks:

• Selecting a Predefined EDGE Setup on page 271

• Generating the Waveform on page 271

• Configuring the RF Output on page 272

Selecting a Predefined EDGE Setup

1. Press Preset.

2. In the ARB Custom Modulation menu (page 271), press Single Carrier Setup > Quick Setup > EDGE.

Generating the Waveform

Press Digital Modulation Off On.

This generates a waveform with the pre–defined EDGE state selected in the step. The display changes

to Dig Mod Setup: EDGE. During waveform generation, the DIGMOD and I/Q annunciators appear and

the pre–defined digital modulation state is stored in volatile memory (BBG). The waveform is now

modulating the RF carrier.
