Trigger level

Trigger level is threshold voltage value the exceeding of which leads to a registration trigger signal forming in digital oscilloscopes.

Trigger level is a registrable parameter and set in voltage value, V. Trigger level is displayed as a horizontal line. In the majority of scope models this trigger level horizontal line is replaced by a short arrow indicator or horizontal marker with T letter to the right or to the left according to the coordinate scale of the oscillogram window.

The picture below shows the sine signal oscillogram, 500 mV_pp. The trigger level is displayed as a horizontal marker with T letter and brightened with a horizontal line, set on 200 mV level. Trigger position coincides with the trigger level of 200 mV excess by the input signal and is displayed with a vertical marker with T letter.
