The image above illustrates a custom version of the Model PB3-300M. The impedance matching network is a typical “L” topology built without a series inductor and using a vacuum variable capacitor in the series tuning position. The PB3 system powers an inductive load that is used to production test florescent lamps. A flat coil ICP (Inductive Coupled Plasma) source is used to excite the lam device as it moves through the manufacturing process. This entire apparatus was designed and manufactured by Manitou Systems.
