CAN and LIN Timing and Protocol Decode
Software
TDSVNM CAN and LIN Timing and Protocol Decode software transforms
Tektronix real-time Windows oscilloscopes into sophisticated in-vehicle
network management tools that provide trigger capabilities, oscillator
tolerance, an
that help to ensure seamless and reliable operation of the network.
Seamless CAN Network Operation
The industry’
tool for debugging problems for seamless operation of a CAN network.
TDSVNM provides oscillator tolerance measurements enabling proper
setting of the sample point in bit time. This ensures accurate sampling of
incoming CAN messages in an asynchronous CAN network. Data rate
measurement quickly identifies mismatch in data rates in any of the CAN
nodes in the n
messages to be generated, hampering network performance.
Electricall
quickly pinpoints problems caused by excessive jitter, amplitude aberration,
spikes, and glitches in CAN messages.
CAN and LIN Protocol Decoding
TDSVNM makes it very easy to interpret NRZ-encoded information in CAN
and LIN messages. This software coverts the time domain information into
data-link layer information (Hex or Binary) in CAN or LIN format, saving
valuable design time. Time stamp information provided by the TDSVNM
software quickly measures the latency time between the two associated
d simultaneous protocol decoding of CAN an d LIN messages
s finest timing measurements in TDSVNM make it an ideal
etwork. Mismatch in data rate can cause a series of error
y, the automotive environment is noisy. CAN eye diag ram analysis
messages for quick cha racterization, and debugging network performance.
Using the zoom features, you can now easily view the specificCAN
message at high
er resolution during long time captures of the CAN/LIN
traffic using the long acquisition memory of the oscilloscope.
The industry’
s first simultaneous protocol decoding of CAN and LIN data
from two segments of an in-vehicle network makes TDSVNM a highly
recommended tool for current and future needs. With this capability,
engineers can easily ensure the accuracy of communication and the
acceptable latency time for exchanging informat ion across a gateway.
Capture CAN and LIN Data
The powerful trigger capabilities offered by DPO7000 Series’ internal CAN
triggers, coupled with the TDSVNM’s graphical user interface, make this
solution one of the best suited to analyze CAN and LIN trafficatspecific
conditions. By triggering on any of the CAN frame types and its bit value,
engineers can debug difficult problems easily.
Characteristics
DPO7000 Integrated CAN Trigger – SOF, Data Frame, Remote Frame, Form Error,
Overload Frame, EOF, and Missing ACK.
