To View And Change Display State Definitions - Agilent Technologies 89410A Operator's Manual

Analyzing Digitally Demodulated Signals (Options AYA and AYH)

To view and change display state definitions

This task shows you how to view and change the state definitions
corresponding to the detection decision points (symbol locations). You can
view and change state definitions for most modulation formats. This task
is a continuation of the previous task.

To learn how to create your own state definitions, see the "STAT_DEF" file
on the Signals Disk. This file contains instructions and sample state
definitions for all modulation formats that have modifiable state definitions.
You can edit the file with any ASCII editor or with the IBASIC editor (if
you have the IBASIC option installed).

and saving a portion of the "STAT_DEF" file.
