Classification: CPC H | IPC H

Claim 7:
8. The method of claim 1,
wherein the RF signal source generates an RF-burst waveform comprising a train of RF-burst pulses, wherein each of the RF-burst pulses has an RF waveform that is present during an RF-burst duration followed by an RF-burst separation time during which there is no RF source signal;
wherein a sum of the RF-burst duration and the RF-burst separation time is equal to the burst period; and
wherein the method further comprises: synchronizing the B-DC-burst waveform with the RF-burst waveform, wherein the synchronizing is delaying the B-DC-burst pulses by a constant burst delay from the RF-burst pulses.
