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
Keysight Signal Generators 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
).
