| A Trigger Modes | Normal (sweep runs when triggered) automatic (sweep runs in the absence of a triggering signal and for signals below 30 Hz). Single Sweep (sweep runs one time on the first triggering event after the rest selector is pressed). LED lights indicate when sweep is triggered and when single sweep is ready. |
| A Trigger Holdoff | Adjustable control permits a stable presentation of repetitive complex waveforms. |
