• AND or OR of each trigger source
• Trigger criteria can be set for each channel.
• Free-running when all are Off
Triggering occurs when the signal rises (or falls) through a specified value.
Triggering occurs when the input signal level enters or exits the amplitude
window defined by upper/lower thresholds.
(where X is "ignore")
(Pulse) Integration 1c, revolution 1/n (where n = pulses/rev)
Time span setting (any span).
Settable with real-time saving.
Open-collector output (with 5 V output, Active Low)
Pulse Width: at least 10 ms
