A power source may generate signals (RF or microwave), when driven by a drive signal from a controller. A sensor may measure the voltage and current of the signals generated by the power source, and may generate sensor signals representative of the measured voltage and current. A sampler may be configured to undersample the sensor signals, synchronously with the drive signal that drives the power source. The sampling frequency may be a scalar multiple of the fundamental frequency of the sensor signals. At RF frequencies, either synchronous undersampling or synchronous oversampling may be performed. At microwave frequencies, synchronous undersampling may be performed. |
