Custom Arb Waveform Generator

Overview

Overview

Custom Arb Waveform Generator mode can produce a single modulated
carrier or multiple modulated carriers. Each modulated carrier waveform must
be calculated and generated before it can be output; this signal generation
occurs on the internal baseband generator (Option 601 or 602). Once a
waveform has been created, it can be stored and recalled which enables
repeatable playback of test signals.
To begin using the Custom Arb Waveform Generator mode, select whether to
create a single modulated carrier or a multiple modulated carrier waveform:
— If you want to create a single modulated carrier waveform, start by selecting
— If you want to create a multiple modulated carrier waveform, start by
186
a Digital Modulation Setup from a set of predefined modes (setups). Once a
predefined mode is selected, you can modify the Modulation Type, the Filter
being used, the Symbol Rate, and the type of Triggering; the Data Pattern is
random by default. This modified setup can then be stored and reused.
selecting a Multicarrier Setup from a set of predefined modes (setups).
Once a predefined mode is selected, you can modify the number of carriers
to be created, the frequency spacing between each carrier, whether the
phase offset between each carrier is to be fixed or random, and the type of
Triggering; the Data Pattern is random by default, the Filter is set to
40 MHz by default, and the Symbol Rate is automatically specified by the
selected Modulation Type being used.
