A real-time trigger figure-of-merit indicator for test and measurement instruments provides an indication of how close a signal-under-test is to satisfying a relevant trigger condition. The indicator includes a first marker that indicates a real-time trigger figure-of-merit that is calculated based on digital samples that represent the signal-under-test, and a second marker that indicates a level that the figure-of-merit must exceed in order for a trigger event detector to detect a trigger event and generate a trigger signal. Thus, by observing the indicator, a user may easily ascertain how close a signal-under-test is to satisfying the relevant trigger condition without requiring the instrument to actually trigger.
