100 SDS2000X User Manual
Interpreting CAN Decode.
Data bytes appear in hex digits in white
Cyclic redundancy check (CRC) appears in hex digits in blue when valid, or in red to
indicate that the oscilloscope's hardware decode calculated a CRC that is different
from the incoming CRC data stream.
Angled waveforms show an active bus (inside a packet/frame).
Mid- level blue lines show an idle bus.
Decoded text is truncated at the end of the associated frame when there is insufficient
space within frame boundaries.
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 (under sampled or indeterminate) are drawn in pink.
