Setting Up Time Correlation Between Analyzers - HP 1660CS-Series User Manual

Setting Up Time Correlation between Analyzers

There are two possible combinations of analyzers: state and state, and
state and timing. Timing and timing is not possible because the
Analyzer Configuration menu only permits one analyzer at a time to
be configured as a timing analyzer. For either combination, time
correlation is necessary for interleaving and mixed display.
Time correlation is useful when you want to store different sorts of
data for each trace, but see how they are related. For instance, you
could set up a timing and a correlated state analyzer and see if setup
and hold times are being met. Or, you could set up two state analyzers
and have one watch normal program execution and the other watch
the control and status lines.
Time correlation requires that state analyzers store time tags. You set
the state analyzer to store time tags by turning on Count Time in the
Analyzer Trigger menu. The timing analyzer already stores time tags
when it samples data.
See Also "Special Displays" in Chapter 5 for more information on interleaving
and mixed display.
