Claim 19:
20. An energy delivery system, comprising:
an RF synthesizer circuit configured to generate an RF electric signal at more than one frequency;
a preamplification stage operably coupled to an output of the RF synthesizer circuit, wherein the preamplification stage comprises an attenuator;
a board controller operably coupled to the RF synthesizer circuit and to the attenuator of the preamplification stage, wherein the board controller is configured to:
modify a gain setting of the attenuator; and
change the frequency of the RF electric signal to impedance match based on a return loss value;

an output connection configured to provide a low-power signal or a high-power signal based on at least the RF electric signal and the gain setting of the attenuator; and
an RF applicator operably coupled to the output connection, wherein the low-power signal or the high-power signal is configured to be provided to the RF applicator and the RF applicator is configured to couple an alternating low-power or high-power RF electric field to animal tissue for respectively sensing the presence of, or processing, the animal tissue
wherein when switching between the low-power signal and the high-power signal, the board controller is configured to modify a gain setting of the preamplification stage without modifying a gain value of an amplifier in the preamplification stage.
