Channel Trigger Trigger modes and appendant registers

Channel window trigger for short inner signals

The analog input is continuously sampled with the selected

sample rate. The upper and the lower levels define a win-

dow. Every time the signal enters the window from the out-

side, the pulsewidth counter is startet. If the pulsewidth

counter stops and the signal is still inside the window, no

trigger will be detected.

If the signal leaves the window before the pulsewidth coun-

ter has stopped, the triggerevent will be detected.

Channel window trigger for short outer signals

The analogd input is continuously sampled with the selected

sample rate. The upper and the lower levels define a win-

dow. Every time the signal leaves the window from the insi-

de, the pulsewidth counter is startet. If the pulsewidth

counter stops and the signal is still outside the window, no

trigger will be detected.

If the signal enters the window before the pulsewidth coun-

ter has stopped, the triggerevent will be detected.
