HP 16501A User Manual

To trigger on a loop that occasionally runs too long
This example assumes the loop normally executes in 14 µs.
1
Select the state analyzer Trigger menu.
2 Define terms LP_START, LP_END, and Timer1 to represent the start
and end addresses of the loop, and the normal duration of the loop.
You can make the sequence specification closer to the problem domain by
renaming Timer1 to LOOP_DUR.
3
Under State Sequence Levels, enter the following sequence
specification:
•
While storing “anystate” Find “LP_START” 1 time
•
While storing “anystate” TRIGGER on “LOOP_DUR 14.00 µs” 1 time Else
on “LP_END” go to level 1
You will need to start the LOOP_DUR timer (Timer1) upon entering
this state. You do this using the Timer Control field in the menu for
sequence level 2.
