CAN Triggering and Serial Decode 25
Keysight InfiniiVision 1200 X-Series and EDUX1052A/G Oscilloscopes User's Guide 281
• Pink vertical bars indicate you need to expand the horizontal scale (and run
again) to see decode.
• Red dots in the decode line indicate that there is data that is not being
displayed. Scroll or expand the horizontal scale to view the information.
• Aliased bus values (undersampled or indeterminate) are drawn in pink.
• Unknown bus values (undefined or error conditions) are drawn in red with a "?"
label.
• Flagged error frames are drawn in red with an "ERR" label.
CAN Totalizer
The CAN totalizer provides a direct measure of bus quality and efficiency. The CAN
totalizer measures total CAN frames, flagged error frames, overload frames, and
bus utilization.
The totalizer is always running (counting frames and calculating percentages) and
is displayed whenever CAN decode is displayed. The totalizer counts even when
the oscilloscope is stopped (not acquiring data). Pressing the [Run/Stop] key does
not affect the totalizer. When an overflow condition occurs, the counter displays
OVERFLOW. The counters can be reset to zero by pressing the Reset CAN Counters
softkey.
