Channel Trigger	Trigger modes and appendant registers

Channel window trigger for entering signals

The analog input is continuously sampled with the selected sample rate. The upper and the lower level define a win- dow. Every time the signal enters the the window from the outside, a triggerevent will be detected.

Channel window trigger for leaving signals

The analog input is continuously sampled with the selected sample rate. The upper and the lower level define a win- dow. Every time the signal leaves the the window from the inside, a triggerevent will be detected.
