# Limit Testing

Subtopics

- Acquisition Limits
- Limit Line Test Limits
- Mask Test Limits
- Measurement Limits
- Reporting Actions

Limit testing lets you stop data acquisition based on acquisition limit, measurement limit, limit line limit, or mask limit events.

To select and configure limit testing, click Measure > Limit Tests > and:

- Acquisition Limits... — This lets you define limits on the number of samples or waveforms. See Acquisition Limits.
- Measurement Limits... — This lets you define limits on measurement values inside or outside of a specified range. See Measurement Limits.
- Mask Test Limits... — This lets you define limits on data points in violation of a mask. See Mask Test Limits.
- Limit Line Test Limits... — This lets you define limits on data points in violation of user-defined line boundaries on the display. See Limit Line Test Limits.

When the specified limit conditions are met, the active tasks stop and, if defined, a reporting action is taken for each limit test. See Reporting Actions.

You can run one or more limit tests at a time. As soon as the limit conditions for one of the tests is met, data acquisition and all tests stop. To reset any of the limit tests, click Clear on the menu bar or change any of the following parameters: vertical scale, offset, horizontal position, horizontal scale, trigger settings, acquisition record length, or averaging.
