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. T
he 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, follow 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 Horizontal Resolution screen button.
4. Select Normal acquisition resolution.
5. Push the Single Seq (single sequence) button.
