  • Triggering for waveform recording
    Patent number: 4755887
    Abstract: A drop out trigger captures waveform data when a normally continuous input signal is disrupted or interrupted. In the preferred embodiment, a conventional trigger detects a parameter periodically satisfied by the continuous signal and resets a timer whenever a trigger event occurs. The alarm count of the timer is set for an interval slightly larger than the periodic interval. If the timer reaches the alarm count, a measurement signal is generated.
