The event table displays the detailed decoding information (include the
decoded data (TX and/or RX) as well as the corresponding line number, time
and error information (TX and/or RX)) 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
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.

press Export to export the decoded data list to the external USB storage
device in CSV format.
11. Error expressions during decoding
Check error and end of frame error may occur during RS232 decoding. When
decoding error occurs, red error mark
horizontal time base) is displayed.
Check Error

When a check bit error is detected during the decoding, a red error mark
will be displayed. For example, when the transmitting terminal is set to
none check and the decoder is set to odd check, the following check error
occurs. Wherein, there is an odd number (1) of 1 in the 8-bit data 00000100
and the check bit should be 0. But, the check bit detected on the TX is 1;
thus a check error occurs.

to select the specified line and view the corresponding decoding
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.
