Abstract
An RF generator includes: a modulation circuit outputting a pulsed RF signal; a variable attenuation circuit adjusting the level of the pulsed RF signal; an output power detecting unit detecting an output power value of the power output from the device; a first comparative arithmetic circuit outputting a first level control signal for controlling the level of the adjusted pulsed RF signal on the basis of a first detected voltage value and a set voltage value set in advance; a second comparative arithmetic circuit outputting a second level control signal for controlling the level of the adjusted pulsed RF signal on the basis of a second detected voltage value and the set voltage value; and a switching circuit switching between the value of the first level control signal and the value of the second level control signal depending on a switching timing setting value.
