Recording Progress
When you begin recording, the left-most segment of the Status bar displays a recording
Progress Indicator (left side of Figure 3.21).
Figure 3.21 Example: Status Bar at Different Recording States
Keep the following in mind when reading the Progress Indicator:
• A black vertical line illustrates the location of the trigger position you selected in the
Recording Options window. The pre-trigger progress is displayed in the field to the
left of the trigger position.
• When the trigger position is reached, the progress indicator wiggles as it waits for
the trigger.
• After the trigger occurs, the field to the right of the trigger fills in the post-trigger color
specified in the Display Options window.
• When recording is complete, the upper half of the Progress Indicator fills in white,
indicating the progress of the data upload to the host computer.
Some other key points about the Progress Indicator:
• If a trigger event occurs during the before-trigger recording, the before-trigger color
changes to the after-trigger color to indicate that not all the expected data was
recorded pre-trigger.
• When you click Stop before or after a trigger event, the Progress Indicator adjusts to
begin uploading most recently recorded data.
• If you wish to abort an upload that is in progress, click the Stop button again.
• The Progress Indicator fills with color in proportion to the specified size and actual
rate at which the hardware is writing and reading the recording memory. However,
the Progress Indicator is normalized to fill the space within the Status bar.
