Figure 15.24 1553B Decoding Event Table
TIP
• When you adjust the horizontal time base, the waveform displayed on the screen will also
change, and the total number of lines containing the decoding information in the event
table will also be changed.
• The displayed decoded data information in the bus is related to the value of the
horizontal time base. Reducing the horizontal time base can help you view the detailed
information.
Export
When the oscilloscope is in "STOP" state, you can export the time and its
corresponding decoded data in the event table.
In Decode menu, click or tap Export, then the save setting interface is displayed. You
can export the data to the internal memory or the external USB storage device (only
when detected) in *.csv format. For details, refer to
Store and Load
.
