Test procedure example using the damped oscillatory wave simulator
① Place the main simulator unit (hereinafter referred to as Main unit) onto the outside of the ground reference plane.
② Connect the standard attached power supply cable to AC in on the backside of Main unit.
③ Connect the connection cables for DUT to HOT terminal and ground terminal on Main unit (insert a capacitor to HOT side), and do the other side of the cables to the testing harnesses. * The connection cables to be prepared by the users.
④ Set the parameters on the controller on the front panel of Main unit and start the test.
