Time Interval example
Example
A team of applications programmers is writing a math package for a
spreadsheet. They need to develop standards for the various math
functions. Using time interval mode, they can test the execution time
of each of the math functions.
For each math function, they enter the starting and ending addresses
in the Time Interval menu. They run the math function while
monitoring its execution time with their logic analyzer in the Time
Interval mode. Using Auto-range, they can quickly vary the time
interval ranges for either greater time coverage or greater time
resolution.
If the programmers wanted to see the details of the time intervals, they
could set up a state analyzer measurement (not using SPA) and
capture the activity between the start and stop events. The details
could then be viewed in the state listing menu.
The figure below shows a sample Time Interval menu and its display.
