Capturing a Single-Shot Signal
In this example, the reliability of a reed re lay in a piece of equipment has been poor, and you need to investigate the problem.

To set up for a single-shot acquisition:
1. Adjust the Vertical Scale and Horizontal Scale to appropriate ranges for the signal you expect to see.
