Custom Digital Modulation (Option 431)
Custom Modulation
Custom Modulation
Custom Modulation has built–in modulation standards such as TETRA and DECT; and pre–defined
modulation types such as BPSK and 16QAM that can be used to create a signal in addition, it
provides the flexibility to modify the digital format’s attributes.
ARB Custom Modulation Waveform Generator
The signal generator’s ARB Waveform Generator mode is designed for out–of–channel test
applications. This mode can be used to generate data formats that simulate random communication
traffic and can be used as a stimulus for component testing. Other capabilities of the ARB Waveform
Generator mode include:
configuring single or multicarrier signals. Up to 100 carriers can be configured.
creating waveform files using the signal generator’s front panel interface.
The waveform files, when created as random data, can be used as a stimulus for component testing
where device performance such as adjacent channel power (ACP) can be measured. The
AUTOGEN_WAVEFORM file, that is automatically created when you turn the ARB Waveform Generator
on, can be renamed and stored in the signal generator’s non–volatile memory. This file can later be
loaded into volatile memory and played using the dual ARB waveform player.
For more information, refer to “Waveform File Basics” on page 132 and “Modes of Operation” on
page 4.
