In addition to generating interference, the EMS measurement software is responsible for monitoring, where the two main tasks are stimulation and monitoring of the EUT. The following integrated stimulus functions make it possible to control the EUT at defined points in the test sequence:
The monitoring functions of the R&S® IMS operating system permit fully automatic monitoring of the EUT. The objective is to obtain a GO or NOGO (PASS / FAIL) result for the test frequency and the test level. Monitoring channels can be defined for this purpose. A GO / NOGO decision is reached by using a definable threshold or a decision window. The measured values are displayed in a result table or in a graph. In addition, a separate table is generated that contains only the NOGO frequencies.
Physical quantities (voltage, current, frequency, temperature) can be monitored either acoustically (sound level) or visually (camera). In the case of tests in the automotive range, vehicular bus systems (CAN, LIN, MOST, FlexRay) can also be monitored.
