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 Press [Save/Recall] > Recall > Recall > LIN Symbolic data (*.ld f) .
2 Press Press to go and navigate to the LIN description file on a USB storage
device.
3 Press Load to: and select which serial decode ( S1 or S2 ) the symbolic information
will be used with.
4 Press Press to Recall .
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 [Serial] .
2 Press the Display softkey and select Symbolic (instead of Hexadecimal ).
Your choice affects both the decode waveform and the Lister window.
LIN Triggering
To set up the oscilloscope to capture a LIN signal, see “Setup for LIN Signals" on
page 407.
LIN triggering can trigger on the rising edge at the Sync Break exit of the LIN
single-wire bus signal (that marks the beginning of the message frame), the
Frame ID, or the Frame ID and Data.
A LIN signal message frame is shown below:
