Note graph representing RFPS input voltage (orange) and RFPS current before, during and after
ignition then varying power settings.
After plasma stabilization FET bias voltages 1 and 2 settle to ~1.9V. RF DC power supply settles
to ~194V @8.2A for a power setting of 1.2kW.
Frequency settles to ~26.5MHz and will change depending on whether a solution is being
aspirated and the makeup of the solution being aspirated.
Plasma run status typical Gas flows and pressures (Poly boost purge and cone purge on also).
