ABSTRACT:
A visual indication of the location and duration of a measurement gate relative to the signal being measured is provided on a display. In response to a start gate signal measurements are initiated and a predetermined change is effected in the normally displayed visual indication of the signal being measured. In response to a gate close indication, measurements are terminated and the normally displayed visual indication is resumed. The normal and changed visual indications are effected by a display control signal produced by summing the signal to be measured and an event gate signal at a point in the circuit near where the event gate signal is generated.
