State Trace
Specification
Menu
The State Trace Specification menu allows you to specify a sequence of states required for trigger. The default setting for the menu looks like that shown below.
Figure 5-47. State Trace Specification Menu
The menu is divided into three sections: the Sequence Levels in the large center box, the acquisition fields at the right of the screen, and the qualifier and pattern fields at the bottom of the screen.
Before describing the fields in the menu, we need to define a few terms. These terms will be used in the discussions on the fields, so understanding their meanings is essential.
Pattern Recognizers: a pattern of bits (0, 1, or X) in each label. There are eight recognizers available when one state analyzer is on. Four are available to each analyzer when two state analyzers are on. The pattern recognizers are given the names a through h and are partitioned into groups of four,
Range Recognizer: recognizes data which is numerically between or on two specified patterns. One range term is available and is assigned to the first state analyzer that you turn on or if only one analyzer is on, then the range term is assigned to it.
