Figure 2-6.

High-Hysteresis Analog Triggering Mode

In high-hysteresis analog triggering mode, the trigger is generated when a

signal crosses above the hysteresis value and then crosses above the trigger

value. The signal must cross back below the hysteresis value before another

trigger is generated.

Figure 2-7. Low-Hysteresis Analog Triggering Mode

In low-hysteresis analog triggering mode, the trigger is generated when the

signal crosses below the hysteresis value and then crosses the trigger value.

The signal must cross back above the hysteresis value before another

trigger is generated.
