Abstract
The functionality and the mode of operation are evaluated in an electrosurgical generator by determining whether a patterned pulse signal that contributes to the generation of electrosurgical energy is as expected. A number of pulses in the patterned pulse signal is compared to an expected number of pulses, and an error condition is indicated when the two values are not the same or differ by more than a predetermined amount. The expected number of pulses depends on a mode of operation of the electrosurgical generator. The error condition may be used to as a basis to terminate the output power delivery.
