4.6 Status Bar
The Status Bar is located at the bottom of the main display window.
Depending on the current activity, the left side of the bar has segments that indicate the
hardware, status, size, activity, and buffer.
The right side of the bar has segments that indicate port status, link status, and
search direction.
4.6.1 Recording Progress
When you begin recording, the Status Bar displays an indicator.
As recording progresses, the indicator changes to reflect the recording progress
graphically:
A black vertical line illustrates the location of the Trigger Position that you selected in
Recording Options.
• Pre-Trigger progress is in the field to the left of the Trigger Position in the
before-trigger color specified in the Display Options.
• When the Trigger Position is reached, the indicator wiggles as it waits for the
trigger.
• After the trigger occurs, the field to the right of the Trigger Position fills with the
after-trigger color specified in the Display Options.
• When recording is complete, the upper half of the progress indicator fills with
white, indicating the progress of the data upload to the host computer.
You should be aware of two exceptional conditions:
• 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 Status Bar adjusts
accordingly to begin uploading the most recently recorded data.
The 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 indicator is
normalized to fill the space within the Status Bar.
