Power Supply Function

The following is a general overview of this function menu, and the detailed pa-

rameters of the waveform corresponding to each protocol/standard can be

found in the corresponding chapter.

If there is a waveform parameter related to setting the voltage val-

ue, when the upper limit of the voltage setting defined in the reg-

ulation exceeds the rated voltage of the instrument, the rated

voltage of the instrument is set as the upper limit. Otherwise, the

output waveform may be distorted.

Recall the Vehicle Waveform

Select any of the above five kinds of vehicle waveforms, after completing the

waveform parameter setting (see the subsequent introduction for each parame-

ter), the system will automatically enter the waveform recalling mode and wait

for the triggering operation. At this time, the VFD screen is displayed as the

main interface of the system, and the corresponding waveform name is dis-

played in the lower right corner.

Run the Vehicle Waveform

After turning on [On/Off], the output of the vehicle waveform is triggered accord-

ing to the selected trigger method.
