Custom Digital Modulation (Option 431)
Using the Arbitrary Waveform Generator
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 261
• Generating the Waveform on page 261
• Configuring the RF Output on page 262
Selecting a Predefined EDGE Setup
1. Press Preset.
2. In the ARB Custom Modulation menu (page 261), 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.
