Claim 11:
12. A method of delivering energy to animal tissue, comprising:
synthesizing an RF electric signal;
adjusting attenuation of the RF electric signal to selectively provide a low-power signal or a high-power signal; and
generating an alternating RF electric field from an RF applicator based on the low-power signal or the high-power signal to couple a low-power or high-power alternating RF electric field to animal tissue for respectively sensing the presence of, or processing, the animal tissue;
wherein adjusting attenuation of the RF electrical signal comprises:
providing a first gain setting to provide the low-power signal and measuring a baseline return loss value corresponding to no animal tissue in a processing position of the RF applicator; and
providing a second gain setting having a lower magnitude than a magnitude of the first gain setting to provide the high-power signal 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.
