Figure 5 Test Circuits
For isolated testing the CAN Bus Substitute 1 is connected to the CAN Transceiver (see
Figure 5). The capacitors C1-2 simulate the cable. Allowed minimum values of the
termination resistors RRTH and RRTL are 500 â¦. Electromagnetic interference on the bus
lines is simulated by switching to CAN Bus Substitute 2. The waves of the applied
transients will be in accordance with ISO 7637 part 1, test 1, test pulses 1, 2, 3a and 3b.
