LINbus Basic Right-Hand Dialog
The Basic right-hand dialog provides detailed controls and setup conditions as follows:

Viewing - Select to view the protocol data in either Binary or Hexadecimal (Hex) formats.
Note: If the trigger is set up first, the setup format (Binary or Hex) made from the trigger dialog is
displayed here.

Level Type and Level - The message decoding algorithm setup is performed here. The level is normally set
up in %, and defaults to 50%. Adjust the level by touching inside the field to highlight the box title, then
use the oscilloscope front panel Adjust knob to make the change. Alternatively, touch inside the number
area twice and select a value using the pop-up keypad.
PLEASE NOTE THE FOLLOWING:

The set Level appears as a dotted horizontal line across the oscilloscope grid.

If your initial decode indicates there are a number of error frames, verify your level is set to a
reasonable value.

Bitrate - Adjust this bitrate value to match the one on the bus to which you are connected. This bit rate
selection is dynamically linked to the decoding bitrate (they are always the same value). Use the arrows
to move through standard bit rates (1.2, 2.4, 4.8, 9.6, 10.417, or 19.2 kb/s) and make a selection. Or,
touch the number twice (with a finger, or using a mouse) and open a pop-up keypad and enter the value
directly. Any value from 1-20 kb/s may be entered this way.
Creating a LINbus Trigger Condition
The following trigger setup detail topics show the dialog selections for a LINbus Trigger with detail on some of
the setup conditions.
Note: Refer to Using The D Supported Protocol Toolsets (on page 14) to correctly access the Trigger Condition
dialog specific to your desired protocol.
The Source Setup information must be defined. The datasheet for your part should contain the information you
need to properly setup the LINbus Trigger.
Previous Trigger Type selections result in dynamic changes to the LINbus Trigger dialog.
