New application software from Tektronix aids efficient testing and debugging of low speed serial buses including CAN (Controller Area of Network) and LIN (Local Interconnect Network) networks. Tektronix' TDSVNM is available on the TDS5000B and the TDS7000B Series digital phosphor oscilloscopes (DPOs), both featuring the MyScope customisable user interface. Use of low speed serial buses is increasing, especially with in-vehicle networks connecting doors, seats, dashboard, airbag, engine parts, steering and gearbox.
To effectively design and integrate network nodes, engineers need to measure node performance including oscillator tolerance, propagation delay, CAN eye diagram, and to analyse protocol activities to ensure reliable performance of the vehicle network.
TDSVNM is the only software application that performs CAN and LIN timing and protocol analysis, measures oscillator tolerance and propagation delay, guides the user in setting the optimum sample point, and simultaneously decodes time-correlated CAN and LIN messages.
Advanced if-then-else trigger capabilities helps the designer to ensure reliable and seamless operation of the CAN/LIN network.
'Adding application specific intelligence to general purpose test instruments is an additional value that Tektronix brings to customers', said Colin Shepard, Vice President, Performance Oscilloscopes, Tektronix.
'The Tektronix TDSVNM package enables the efficient testing and debugging of CAN and LIN networks, which will be particularly useful to engineers in the automotive and process control electronics industries who make extensive use of the serial data technologies'.
'They will find TDSVNM software to be a superior package'.
Through integrated timing analysis with protocol information, designers can use TDS5000B and TDS7000B series oscilloscopes to quickly isolate the problems to either physical layer or data link layer.
Oscillator tolerance and propagation delay measurements quickly brings out synchronisation problems whenever a new CAN/LIN node is added to the network.
An ability to simultaneously decode CAN and LIN messages using two channels enables designers to monitor different segments of the network for locating communication problems across gateways.
Measuring a CAN eye diagram enables the designer to observe the noise content in the CAN message.
TDSVNM software enables customers to set trigger conditions based on the content of a CAN message.
Trigger conditions are then downloaded at run-time to an ATM1 Automotive trigger module developed by Crescent Heart Software (CHS) that provides advanced CANbus trigger capabilities to the TDS5000B and TDS7000B oscilloscope.
The ATM1 module triggers on conditions in real time.
TDSVNM along with ATM1 helps to pinpoint the cause of a problem through a unique ability to trigger with if-then-else conditions for CAN and LIN network problems, enabling customers to solve electrical problems at the physical layer, and software issues at OSI layers.
