• The shunt resistor Rs as shown in figure 1 a), b), c) of ISO 7637-2 shall not be installed.• Ensure that the 50 Ω termination is installed on the RF sampling port of the AN.• The bandwidth of the digital oscilloscope used for measurement should be no less than 400 MHz and its sampling rate should be no less than 2 GS/s.• Motors and actuators that can stall during normal operation shall, in addition to the Off-to-On and On-to-Off modes, be tested in a “stall” condition. The stall should not be held longer than one second. This is to prevent activation of in-line protection devices (such as Positive-Temperature Coefficient [PTC] resistors) that would interrupt the current to the DUT.• Ten (10) waveform acquisitions are required for each mode of operation (e.g. On-to-Off, Off-to-On, etc). Only those waveforms with the highest positive and negative amplitudes shall be reported in tabular listings. The relevant parameters such as the rise/fall time, pulse width and amplitude of the pulse shall be documented in the report. According to the collected waveforms, the applicable limits of the test results can be judged. The corresponding pulse limits are shown in Table 10.• Compliance to this requirement by the DUT may be waived if it is powered from an external, regulated supply located in another ECU. However, the overall subsystem is required to comply with these requirements. It should be agreed in the test plan. Contact CEVT EMC department for guidance.• In the test plan and report, the type of switch (electronic switch/mechanical switch) used in waveform acquisition shall be recorded.
