An automotive manufacturer has a switch/relay (the Device Under Test or DUT (https://en.wikipedia.org/
There are three ADwin series: ADwin-light-
Classing of Transients
In many test applications, users apply an analog and/or digital stimulus to the DUT, using single or multiple channels of actuators or amplifiers. In addition to providing the stimulation, the ADwin system acquires the response of the components by reading its own input channels and evaluating the response in real-time. Thus, the system can immediately calculate how well the DUT matches the required specifications.
ADwin systems perform all the necessary tests and also perform post-test data analysis. Here the ADwin measures and categorizes time in classes. Classes are time period ranges (i.e. the time resolution, for example 500 nanooseconds to 1 microsecond)
During acquisition the ADwin test system checks to see if the signal is above the set level and if so, it then measures the duration and the value's threshold. Online evaluation of measurement data is performed immediately after each sample is taken.
Test information and measurement data is transferred to a control system and displayed on the PC through a graphical user interface (GUI). The ADwin automatically generates a table of the data and this information can then be stored as quality records in the production database.
