Claim One:
1. A method for using multiple fixtures for applying a variety of plasma conditions to determine fixed parameters of a match network model, comprising: receiving a first output impedance measured at an input of a first fixture; receiving a first input impedance measured at an input of an impedance matching network, wherein the first input impedance is measured when an output of the impedance matching network is connected to the input of the first fixture; receiving a second output impedance measured at an input of a second fixture; receiving a second input impedance measured at the input of the impedance matching network, wherein the second input impedance is measured when the output of the impedance matching network is connected to the input of the second fixture; applying the first measured output impedance and the second measured output impedance at an output of a match network model to calculate a first predicted input impedance at an input of the match network model and a second predicted input impedance at the input of the match network model when the match network model is assigned a first fixed inductance, a first fixed capacitance, and a first fixed resistance; determining whether the first predicted input impedance is within a predetermined range from the first measured input impedance and whether the second predicted input impedance is within the predetermined range from the second measured input impedance; and assigning the first fixed inductance, the first fixed capacitance, and the first fixed resistance to the match network model upon determining that the first predicted input impedance is within the predetermined range from the first measured input impedance and that the second predicted input impedance is within the predetermined range from the second measured input impedance.
