Analog Edge Triggering
Configure the analog trigger circuitry to detect when the analog signal is
below or above a level you specify.
In below-level analog triggering mode, shown in Figure 11-3, the trigger is
generated when the signal value is less than Level.
Figure 11-3. Below-Level Analog Triggering Mode
In above-level analog triggering mode, shown in Figure 11-4, the trigger is
generated when the signal value is greater than Level.

Analog Edge Triggering with Hysteresis
Hysteresis adds a programmable voltage region above or below the trigger
level that an input signal must pass through before the DAQ device
recognizes a trigger condition, and is often used to reduce false triggering
due to noise or jitter in the signal.
