Window trigger
D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

The trigger is made at the signal input into the threshold window or the signal output out of it. Input into the window is the situation when the input signal gets higher than the low threshold level or lower than the high threshold level. Output out of the window – when the input signal gets higher than the high threshold level or lower than the low threshold level.

The following picture shows the detection of beyond-cutoff overshot in the signal under research.
Pic.2 The example of negative pulse trigger that goes beyond the window for ACK-3102 1T PC-based oscilloscope.
Input to window trigger is used rarer. In the majority of cases it can be replaced by edge trigger. But still it’s considered useful when it’s known in advance from which side the signal can input into or output out of the specified amplitude area.
