Precautions for high-speed load simulations
During high-speed load simulation, do not connect the common terminal of the external
device to the terminal of the DUT (the terminal that is connected to the negative input terminal
of the PLZ-4WL). Attach a commercially available ferrite core to the wiring between the PLZ-
4WL and the external device.
