Trace Function Configuration
A window with trace configuration parameters is presented.
Use the editable fields to change parameters contents.
The editable fields have the factory default value (if no file was selected), or the values from the previously saved file.

While the status is not complete, the Ok button is disabled and the acquisition can not be performed.
When the status is complete, all programmed trace channel’s data is acquired.
When the acquisition is complete please type the file name where all trace information and channel’s data is to be stored.

| • | Sample time - time of the selected sample in the chart. |
| • | Sample value - value of the selected sample in the chart. |
| • | Unit - trace channel’s data unit. |
| • | Minimum - shows/changes the lower bound for the axis of this channel in the graph. |
| • | Maximum - shows/changes the upper bound for the axis of this channel in the graph. |
A black vertical line is shown at the trigger position. At the top of the graph is the trigger description.
