4.10.3 Adjustment characteristics
The user can adjust the response characteristics for the load to be actually used.
Through adjustment, it is possible to minimize distortion of the output waveform for a broad range of
load conditions including the resistance load as well as inductive load and capacitive load. Adjustment
to lower speed and higher speed compared to fixed characteristics is possible.
Adjustment is performed by moving three adjustment knobs corresponding to the time constant, voltage
feedback amount, and current feedback amount, while observing the output voltage and output current
waveform with an external oscilloscope. The loop characteristics of the amplifier can be changed with
these three adjustment knobs, and the output impedance characteristics changed by an equivalent
amount. As a result, distortion of output waveform can be minimized for a broad range of load
conditions.

Operation procedure
<1> Switch off the output.
<2> To be able to observe the output voltage waveform and output current waveform, connect an
external oscilloscope and the voltage/current monitor terminals (MONITOR OUT) with a
BNC cable.
<3> Adjust each volume of the response calibration (RESPONSE CAL) as shown in step <4>.
T volume: Adjusts the time constant.
V volume: Adjusts the voltage feedback amount.
I volume: Adjusts the current feedback amount.
