This PCI fault insertion switch range is available with 75, 64 or 36 channels. It is primarily designed for the simulation of fault conditions in automotive & avionics applications involving the reliability testing of safety critical controllers. The Stimulus/Measurement to UUT path is suitable for supporting CAN and FlexRay bus systems. It is designed to be able to insert different types of fault condition between the test fixture and the equipment under test. Thru relays on each channel allow the simulation of an open circuit between the stimulus/measurement connection and the UUT connection. Fault insertion buses allow any channel to be shorted to any other channel and also enable any channel to be connected to an external fault condition.
