Pattern Trigger
The Pattern trigger identifies a trigger condition by looking for a specified pattern. The pattern
trigger can be expanded to incorporate delays similar to other triggers. Pattern durations are
evaluated using a timer. The timer starts on the last edge that makes the pattern “true”. Potential
triggers occur on the first edge that makes the pattern false, provided that the time qualifier
criterion has been met. The oscilloscope provides 4 patterns: logical AND, OR, NAND and NOR
combination of the channels. Each channel can set to low, high or invalid.
