A method for optimizing emissions from simultaneous activation of electrosurgery generators is presented including delivering first energy to a first target tissue via a first energy module, the first energy represented as a first waveform having a first phase, delivering second energy to a second target tissue via a second energy module, the second energy represented as a second waveform having a second phase, applying the first energy in a first energy mode, and applying the second energy in a second energy mode. The method further includes the steps of comparing the first phase of the first energy waveform with the second phase of the second energy waveform and adjusting a relative phase between the first and second energy waveforms based on the comparison step.
