Figure 7-4 I2C Decoding
The event table displays the detailed decoding information (include the
decoded data as well as the corresponding line number, time, data direction,
ID information and 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
device in CSV format.
