Capturing a Single-Shot Signal
The reliability of a reed relay in a piece of equipment has been poor
and you need to investigate the problem. You suspect that the relay
contacts arc when the relay opens. The fastest you can open and
close the relay is about once per minute so you need to capture the
voltage across the relay as a single-shot acquisition.
To set up for a single-shot acquisition, do these steps:
1. Adjust the vertical SCALE and horizontal SCALE to appropriate
ranges for the signal you expect to see.
2. Push the acquire MENU button.
3. Push the Resolution screen button.
4. Select Normal acquisition resolution.
5. Push the SINGLE SEQ (single sequence) button.
The SINGLE SEQ button sets trigger parameters to the correct
settings for a single-shot acquisition.
