ABSTRACT:
An apparent zero delay of a trigger view signal with respect to a normal vertical signal in an oscilloscope is provided by horizontally shifting the trigger view display to coincide with the normal vertical display. This is achieved by injecting a predetermined offset current into the sweep sawtooth output amplifier only when the trigger view signal is being displayed.
