3.1 Test Set-up

Figure 3-1 shows the specific hardware connections between evaluation board and test equipment. Both power supply and CAN bus wiring harnesses are included in the injection probe. In this test, connections to MSP430 microcontroller monitoring electromagnetic interference reactions of the DUT is accomplished by using fibre optics leads.

Figure 3-2 to Figure 3-5 show the equipment and EVM configuration of the BCI test.
