KES7711A, KES7713B and KES7714 generate test
pulses 1 required by the ISO and SAE standards. Test
pulse 1 is used to simulate the transient phenomenon
that occurs when the power supply is cut off from the
inductive load.

■ DC cut time can be set within a range of 2 ms to 200 ms.
■ Since it also outputs positive polarity waveforms whose polarity has been reversed, it supports not only ISO standards but also independent standards of automobile manufacturers as well.
■ Output impedance： Since 2Ω, 4Ω, and 10Ω can be selected, it supports not only ISO standards but also independent standards of automobile manufacturers as well.
