Using Custom Digital Modulation for N5172B/82B with Option 431 and 653/655/656/657
Using the Arbitrary Waveform Generator
Using the Arbitrary Waveform Generator
This section teaches you how to build dual arbitrary (ARB) waveform files containing custom digital
modulation for testing component designs.
Custom ARB digital modulation creates waveforms using modulation types, filtering, symbol rates,
and other parameters defined by digital communications standards. These waveforms are
formatted as unframed data.
Figure 9-17 Adding Custom Modulation to a Waveform
Using Predefined Custom Digital Modulation
This section teaches you how to perform the following tasks:
— Selecting a Predefined EDGE Setup on page 276
— Generating the Waveform on page 276
— Configuring the RF Output on page 277
Selecting a Predefined EDGE Setup
1. Press Preset.
2. In the ARB Custom Modulation menu (page 276), 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.
