2.14.1 Memory Settings
The Trace Memory Status section has the following fields.
Trigger Position
Pre‐Trigger memory defaults to 50%, which defines the percentage of data to capture
before and after the triggering event. You can change this percentage by dragging the
slider.
Capture of the specified percentage of the data prior to the triggering event cannot be
guaranteed and may be 0. This can occur if the triggering event occurs before storing the
required amount of pre‐trigger event data. In such a case, the data display shows fewer
than the specified data points prior to the triggering event. For more detail,
See “Pre‐
Trigger” on page 90. .
Note: Trigger Position only works when the triggering option is Pattern.
