FlexRay Totalizer
The FlexRay totalizer consists of counters that provide a direct measure of
bus quality and efficiency. The totalizer appears on screen whenever
FlexRay Decode is ON in the Serial Decode Menu.
• The FRAMES counter gives a real-time count of all captured frames.
• The NULL counter gives the number and percentage of null frames.
• The SYNC counter gives the number and percentage of sync frames.
The totalizer runs, counting frames and calculating percentages, even when
the oscilloscope is stopped (not acquiring data).
When an overflow condition occurs, the counter displays OVERFLOW.
The counters can be reset to zero by pressing the Reset FlexRay Counters
softkey.
