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 ope n and
close the re lay is about once per minute so you need to capture the
voltage across t he re lay 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 scree n 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 acqui siti on.
