Dual
-
window trigger mode
The dual
-
window trigger mode is a more sophisticated version of the window
trigger mode. Now both levels are used as an arm/trigger/disarm level. This
allows the trigger detector to react to a dip in both directions.

Figure 10.7: Dual

window trigger mode
A Trigger
Diagram 1 shows one situation, whereas Diagram 2 shows the other situation
with the same settings. In this mode, the following conditions determine the
trigger result:
l
Level crossing in opposite set direction = arm level
l
Level crossing in set direction = disarm when other level is armed
l
Level crossing in set direction = trigger when level is armed
Since this is true for both levels, a “dip” in both directions is detected, as shown
in Diagrams
1 and 2 (see Figure 10.7).
Relevant settings for this mode:
l
Mode: dual
-
window
l
Primary level: any value within the input range
l
Secondary level: any value within the input range
l
Direction: positive or negative for primary level; secondary level is
automatically set to the opposite direction
l
Hysteresis: any relevant value is used for both levels.
