Using State Overview, State Histogram, and Time Interval
This section explains how to select the display fields, set up the logic
analyzer and use the State Overview, State Histogram and Time
Interval modes of SPA.

Setting up the logic analyzer

This section assumes you have defined the Format and have connected
the logic analyzer probes to the target system. For complete details on
these topics, refer to the appropriate reference section for your
analyzer.
For a detailed description of State Overview, State Histogram, and
Time Interval mode measurement processes, refer to the previous
section, "SPA measurement processes."

Using State Overview mode

Choosing a label to monitor. To specify a label to monitor, select the
"Label" field in the State Overview menu. The pop-up shows a list of all
the labels defined in the Format Specification. From this list, choose
the label you want to monitor.
NOTE: Changing from one label to another will erase the display setup for the first
label. If you want to change to a different l abel, but don’t want to lose the
setup for the current one, first save the current one to disk or print it.
