
Response characteristics switching
Fixed characteristics or adjusted characteristics

Response calibration function
If adjusted characteristics are selected as the response characteristics, the response characteristics
adjusted by the user can be used. The distortion of the output waveform associated with the load
conditions can be improved through adjustments. Higher or lower speed than the fixed
characteristics can be achieved through adjustments.
Adjustments are performed by operating the three adjustment knobs for the time constant, voltage
feedback amount, and current feedback amount, while watching the output voltage and current
waveform on an external oscilloscope.
