P1 is the transient phenomenon generated when the analog power supply is disconnected from the inductive load. It is applicable to the situation that various DUTs are directly connected in parallel with the inductive load when they are used on the vehicle; P2a simulates the transient phenomenon caused by the sudden interruption of the current in the device in parallel with the DUT due to the inductance of the harness. The on-board electronic transient interference simulator RV p1p2a meets the latest requirements of iso-7637-2 and gb/t21437.
