RIGOL Chapter 8 Protocol Decoding
8-30 MSO4000/DS4000 User’s Guide
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
device in CSV format.

expressed by turquoise patch. It is expressed by red patch when error
