Abstract
A method according to the present disclosure includes: searching for an initial phase of a modulation signal at which an absolute value of a reflection coefficient or a power value of a reflected wave power at an output terminal of a first power supply calculated in a second power supply ON period is minimized in a state where a first matching operation in a first matching unit is stopped; searching for a frequency shift at which the absolute value of the reflection coefficient or the power value at the output terminal calculated in the second power supply ON period is minimized in a state where the first matching operation is stopped; and searching for an offset frequency at which the absolute value of the reflection coefficient or the power value at the output terminal calculated in a second power supply OFF period is minimized in a state where the first matching operation is stopped.
