Chapter 7 Protocol Decoding RIGOL

Figure 7-6 CAN Decoding
The event table displays the detailed decoding information (include the
decoded data as well as the corresponding line number, time, frame ID, data
length code (DLC), cyclic redundancy check (CRC) and acknowledgment
(ACK) information) of the waveform on the screen in time order. At most 10
lines of decoding information can be displayed on one page (the line number
starts from 0). You can turn the multi-function knob
to select the
specified line and view the corresponding decoding information. The line
currently selected is highlighted with brown shading and the decoded data
of this line is dispalyed at the lower-left side of the event table.
Note:
The display format of the decoded data in the event table is determined
by the bus display format currently selected (refer to “Format”).
When adjusting the horizontal time base, the waveform displayed on
the screen will change and the total number of lines of decoding
information in the event table will change.
The decoded data information displayed in the bus is related to the
horizontal time base. You can view the detailed information by reducing
the horizontal time base.
2) If a USB storage device is currently connected to the instrument, you can
press Export to export the decoded data list to the external USB storage
