Key Points:
1. H (High): Logic high: voltage is higher than threshold setting.
2. L (Low): Logic low: voltage is lower than threshold setting.
3. X (Ignore): Don’t care. If all the channels are ignored, the oscilloscope won’t
be triggered.
4. Qualifier: A timer begins when code terms are satisfied. Duration trigger
occurred in the time set by the qualifier.
