27 LIN Triggering and Protocol Decode
Loading and Displaying LIN Symbolic Data
When you load (recall) a LIN description file (*.ldf) into the oscilloscope, its
symbolic information can be:
• Displayed in the decode waveform and Lister window.
• Used when setting up LIN triggering.
• Used when searching for LIN data in the decode.
To recall a LIN description file into the oscilloscope:
1 From the main menu, choose File > Open....
2 In the Open dialog box, from the Format drop-down menu, select LIN Symbolic
data (*.ldf).
3 From the Load to: drop-down list, select which protocol decode (P1 or P2) the
symbolic information will be used with.
4 Use the controls in the bottom of the dialog box to select the file to be recalled.
5 Select Open.
A message indicating whether the open was successful is displayed.
The LIN description file remains in the oscilloscope until it is overwritten or a
secure erase is performed.
To display LIN symbolic data:
1 Press [Protocol Decode].
2 In the Settings controls, from the Display drop-down list, select Symbolic (instead
of Hexadecimal).
Your choice affects both the decode waveform and the Lister window.
