The differential PXI fault-insertion switch (Model 40-200) is designed for lower data rate serial interfaces such as CAN and FlexRay, and the high bandwidth differential PXI fault insertion switch
(Model 40-201) is designed for higher data-rate serial interfaces such as AFDX and 1000BaseT Ethernet.
Pickering Interfaces makes a range of PXI Fault Insertion Switch
Modules for just this purpose.
The switching topology of the 40-202 fault insertion switches
allows switching channels to be interconnected so that complex fault-insertion channels can be constructed.
