1)Short circuit is defined as a combination of remaining resistances and inductances. See schematic on page11.
2)VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839.
3)See also diagram on page 11.
4)See also on page 8. Slew rate limitation can be achieved by means of using a series resistor RIN in the input path. This resistor is also required for reverse operation. See also page 10.
