High frequency recommended vocabulary
ISO 7637-3 defines the test method for electrical transients that reach a component through conductors other than the supply lines. Modern vehicle architectures distribute signals along a dense network of data and sensor cables, and a transient generated by a switching load on one circuit can be transferred to a neighbouring cable by capacitive or inductive coupling, arriving at an electronic module through an input, output or communication port rather than through its supply terminals. The standard describes the coupling mechanisms involved, then specifies the two practical methods by which the disturbance is applied: a capacitive coupling clamp, which induces the transient into the cable without galvanic contact, and a direct injection arrangement using a series capacitor for lines that can accept it. It defines the waveform of the applied transient, the amplitude levels, the routing of the cable through the clamp and the characteristics of the ancillary equipment, so that the test is reproducible. Assessment follows the functional status criteria declared for the component.
