Claim 0:
1. 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 the board controller is configured to:
provide a first gain setting of the attenuator to provide the low-power signal at the output connection and measure a baseline return loss value corresponding to no animal tissue in a processing position of the RF applicator; and
provide a second gain setting of the attenuator having a lower magnitude than a magnitude of the first gain setting to provide the high-power signal at the output connection in response to detecting a return loss value exceeding a loss threshold value, wherein a return loss value exceeding the loss threshold value corresponds to animal tissue in the processing position of the RF applicator.
