Limitations Affecting Use of Analyzer Resources
There are limitations on the way resources can be combined to form
complex pattern expressions. Resources are combined in a four-level
hierarchy. First, resources are divided into two groups. The groups
can be combined with AND or OR. Second, within these groups,
resources are combined into pairs. Pairs can also be logically
combined using AND or OR. Third, individual resources are combined
into pairs using AND, NAND, OR, NOR, XOR, NXOR. Fourth,
individual resources may be included or excluded from participating in
a pattern expression. You can also include the logical negation of the
resource.
The following table shows how resources are divided in the
HP 16550A. Remember that some resources may not be available,
depending on the analyzer configuration. For example, if you are using
the analyzer as a state analyzer, the Edge1 and Edge2 resources are
not available. If the timers are off, the Timer1 and Timer2 resources
are not available.
