Abstract

See full text

Embodiments of the invention include an apparatus and method for displaying trigger frequency on a display of a test and measurement instrument. During each of a series of equal time intervals, a number of trigger events are counted. Each trigger event count is associated with a corresponding logical column of a trigger display window. The trigger event counts are written to memory locations associated with the corresponding logical columns of the trigger display window. Trigger frequency logic generates multiple trigger frequency indicators based on the trigger event counts. The trigger frequency indicators are displayed in the trigger display window to quickly and efficiently convey trigger density information to a user of the test and measurement instrument. The apparatus includes jitter reduction logic to reduce or eliminate unwanted jitter related to the trigger frequency indicators.
