The JASO D001-94 from the Japanese Automotive Standards Organization departs from the traditional

ISO/SAE pulses in signicant ways. These pulses have a 1 µs rise time, use special output impedances, methods of measuring pulse width, and pulse coupling. The JASO D001-94 forms the basis of other Japanese standards. This is one of a series of Gemini JASO based modules that was developed for usage with a NSG 5500 capacitive discharge immunity simulation system.

These classic pulses are sometimes used as the base for other standards, Nissan for example. Therefore, other pulses are also covered by this module.

* Pulse width values typical - dened by pulse generation circuit, not by pulse characteristics

Note: The pulse shaping networks are designed internally with a 1 µs rise time. However, due to system capacitance of the 100 A coupler, typical rise times measured at the output of the system can be 3 µs or more.
