Custom Real Time I/Q Baseband
Working with Data Patterns
Using a User-Defined Data Pattern
User Files (user-defined data pattern files) can be created and modified using the signal generator’s
Bit
File Editor
or they can be created on a remote computer and moved to the signal generator for direct
use; these remotely created data pattern files can also be modified with the Bit File Editor. For information
on creating user-defined data files on a remote computer, see the programming guide.
These procedures demonstrate how to use the
Bit File Editor
to create, edit, and store user-defined
data pattern files for use within the custom real-time I/Q baseband generator modulation. For this example, a
user file is defined within a custom digital communication.
Creating a Data Pattern User File with the Bit File Editor
This procedure uses the Bit File Editor to create a Data Pattern User File and stores the resulting file in the
Memory Catalog (described on
page 52 ).

This opens the Bit File Editor, which contains three columns, as shown in the following figure.
NOTE
When you create a new file, the default name is
UNTITLED
, or
UNTITLED1
, and so forth.
This prevents overwriting previous files.
