Damped Oscillatory Wave Simulator (SWCS) High Frequency Surge Test
(Burst Waveform) SWCS-931SD
A damped oscillatory wave simulator simulates the fast-repeating, high-frequency noise that occurs when switches turn on and off, and evaluates the resistance of electronic and electrical equipment.
- A maximum output voltage of 1.5 kV
- Repetition frequency variable from 0.4 Hz to 400 Hz
- Output resistance variable from 50 to 200 Ω (10Ω step)

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.
