1. An electrosurgical generator comprising:
an RF output stage configured to output a first radio frequency (“RF”) waveform; and
a controller configured to control operation of the RF output stage, the controller configured to:
pause output of the first RF waveform;
measure RF interference caused by a second RF waveform during pausing of the output;
output a feedback signal to control the RF output stage to output the first RF waveform at a first frequency to avoid the RF interference; and
determine a plurality of frequencies associated with the RF interference.
