16.3 Test Procedures

Test pulses shall be applied to power supply and input circuits in accordance with the requirements delineated in Annex E

and documented in the EMC test plan.

Prior to testing:

• For Pulses G1 adjust the transient generator to the voltage level listed in Figure D-9 of Annex D with the DUT and

"R" disconnected (open circuit condition). Pulse measurement shall be facilitated using an oscilloscope and voltage

probe meeting the requirements delineated in ISO 7637-2.

• For Pulse G2, adjust the transient generator to the voltage level listed in Figure D-10 of Annex D with the DUT and

disconnected but with "R" connected. Pulse measurement shall be facilitated using an oscilloscope and voltage

probe meeting the requirements delineated in ISO.

• For Pulses A and C, verify that the output of the transient test circuit (open circuit conditions) produces waveforms

typical of those illustrated in Annex D.

Connect and activate the DUT. Verify that it is functioning correctly.

Apply each test pulse listed in Table 16-1, except for Pulses G1 and G2, individually to each DUT battery or ignition

circuit in addition to individual input circuits connected to battery or ignition circuits. Test pulses G1 and G2 are

applied to all power and input circuits simultaneously.

Prior to application of either Pulse G1 or G2, connect the 0.5 ohm resistor across the Transient Pulse Generator output

as illustrated in Figure 16-5. Verify the waveforms conform to the loaded waveform requirements listed in Figures

D-9 and D-10 of Annex D prior to application of the waveforms to the DUT.

Monitor DUT functions before, during, and after application of each series of test pulses for the time stated in

Table 16-1.
