Resource terms
Resource terms are user-defined variables that are assigned to
sequence levels. They are placed into the sequence statement where
their bit pattern or edge type is searched for within the data stream.
When a match is found, a branch is initiated and the next statement or
sequence level is acted upon. Resource terms take the following forms:
• Bit pattern terms a-j
• Range terms 1 and 2
• Edge terms 1 and 2 (Timing only)
• Global timers 1 and 2
All resource terms and timer terms are listed in a scrollable Terms field.
To view all offscreen terms, select the Terms field, then use the knob to
roll the terms list onscreen.
When the logic analyzer is configured as a state analyzer, you can use
any of the ten bit pattern terms, range terms, or timers in your trigger
specification. When you configure the logic analyzer as a timing
analyzer, you can use any of these terms plus the edge terms.
Bit pattern terms a-j
You can set a bit pattern consisting of any combination of 1s, 0s, or Xs
(don't cares) for the 10 terms a ƒ j. Bit pattern terms can also take the
NOT form of a - j.
Range terms 1 and 2
Two range terms are available which can be set to a range of bit pattern
values. The first pattern and the last pattern are part of the range
which must be matched.
Range terms take the form of either In Range, or the NOT form of Out
Range.
