Tektronix TDSVNM CAN,LIN Reference manual
TDSVNM CAN and LIN
Timing and Protocol Decode Software
Reference
Getting Started with TDSVNM
You can use this side of the quick reference to start taking
measurements with the TDSVNM CAN and LIN Timing
and Protocol Decode software. The other side contains a
complete menu tree for TDSVNM software.
NOTE. For complete operating instructions
and general safety information, refer to the
online help for the application.
The TDSVNM CAN and LIN Timing and Protocol Decode
software and the ATM-1 Automotive Trigger Module
transform a digital oscilloscope into an analysis tool to
capture and decocde CAN and LIN messages.
Decoding CAN and LIN Protocols
To decode the CAN and LIN messages, follow these steps:
1. To start the application, do one of the following:
H Select File > Run Application > in the oscilloscope
menu bar. Then select CAN and LIN Timing and
Protocol Decode Software
H App > CAN and LIN Timing and Protocol Decode
Software
H Analyze > CAN and LIN Timing and Protocol De-
code Software
2. Select Tests > Select from the application menu. Select
CAN & LIN.
3. Connect the probes to the device under test as shown in
the following illustration.
4. Select Tests > Configure from the application menu, and
then set the following parameters:
H Set the Trigger Using to ATM-1.
H Set the Probe Type to Differential.
H Set the Bus 1 (Trigger Source) parameters: Source to
Ch1, Bus Type to CAN-DW-LH, and Bit Rate to the
bit rate of the selected bus type.
H Set the Bus 2 parameters: Source to Ch2, Bus Type
to LIN, and Bit Rate to the bit rate of the selected bus
type.
H Set the CAN Node Sensor to None.
H Set Analysis to Data.
5. Select Tests > Trigger Setup from the Application menu.
Set the Trigger-In source and the Sample Point Location
as appriopriate. Set the Trigger Event to Elementary
with Trigger Using set to ATM-1.
NOTE. DPO-CAN is available only on DPO
oscilloscopes when CB:CANBus Trigger
option is enabled.
6. Click Define. Define the trigger settings and click OK.
NOTE. To define trigger events, you must have
the ATM-1 Automotive Trigger Module or the
DPO oscilloscope with CB:CANBus Trigger
option enabled
7. Set ACK to No.
8. Push the Run button to start taking measurements.
When the measurement is completed successfully, the
application automatically displays the results. You can
also view the results by selecting Results > Details from
the application menu bar.
9. The application displays the measurement results.
