Quality Assurance Today
A close look to current electronic control units (ECU's) unveils bus systems such as CAN, LIN, FlexRay, partly even K-line etc. Furthermore there is often a mixture of diverse analogue and digital signals. Recently it has become obvious that the “continuously repeated general test task“ does not exist. Test engineers are constantly facing new or changing situations and tasks.
What does it mean for assuring requested quality? Is the “good old tester” disused, because it can't cope with the changed situation any longer? If yes, what can be done?
Immediately, terms like 'investment', 'costs', 'effort' and the like enter the thought stage. Especially in economically tough times such topics are of highest concern and importance. Useful solutions that unites technological as well as economical benefits – a versatilely usable, modular and scalable technology. Virtually, “one for all” at acceptable purchase costs. The facts and thoughts were the main driving and leading motive to develop a completely new communication and test controller generation – the Series 61.
The Series 61 controllers are based on a modular and hence scalable test resource concept. It enables a flexible adaptation to the interface and resource architecture of the respective unit under test (UUT). It is possible to provide up to eight CAN, LIN or K-line interfaces and, additionally, two FlexRay interfaces as well as analogue and digital I/O on the Series 61 controller board. Specifically this means that one single module is sufficient where previously two, three or even more test technology components were required.
Even a completely project specific configurability by the user was considered. For example, exchangeable transceiver modules allow the formatting of CAN interfaces to high-speed, low-speed or single-wire topologies. In the case of possible defects they can be repaired very quickly. Also LIN users “will be thrilled” – for instance a trouble-free reconfiguration between LIN Master and Slave modes is possible any time and very simple per
