4.10 Response

Calibration

4.10.1 Outline

The BP4620 has a response calibration function that allows individual optimization of transient
response characteristics during square wave output or sudden output changes.
The transient response varies with the load for loads that have complex impedance characteristics such
as electromagnetic parts that include inductance (coil components) or capacitance (capacitor
components). The BP4620 allows the user to adjust the response characteristics according to the load.
The response characteristics of the amplifier can be selected from the following two types.



Fixed characteristics



Adjusted characteristics

Switch between fixed and adjusted characteristics in the output off status. Switching in the output on
status is not possible.
