The medical procedure can employ an energy source (20), the energy source can be connected to an energy delivering device (22) via a transmission line (21). The energy delivery system can include a measurement system (30), the measurement system can be configured to sample an output signal (40) generated by the energy source. The energy delivery system includes a control system (60), which includes a calibration unit (61). The calibration unit can be configured to generate a calibration signal (62). The calibration signal can have a magnitude and phase, wherein the magnitude and phase is representative of the output signal and the transmission line loss information. The energy delivery system can also include a control unit (63), the control unit being configured to receive the calibration signal and adjust the energy source as needed. 211/2 CC EE K C J CU)) Ivy-D C) 00§Ij -M CD S.w LO ,IIz 4- 3~ 3 '.0 u =3 LL- M
