Claim:
1. A method of calibrating an impedance tuner by measuring data with an instrument to determine a set of s-parameters of the impedance tuner at multiple impedance tuner states, with the impedance tuner connected in a test setup including the instrument, the method comprising: (i) setting an impedance tuner state to one of the multiple tuner states; (ii) setting a sweep parameter to a value in a set of multiple sweep parameter values, wherein said sweep parameter is frequency; (iii) measuring data at said tuner state and sweep parameter value; (iv) repeating steps (ii) and (iii) for a different sweep parameter value in said set of multiple sweep parameter values until data has been measured for all sweep parameter values in said set; (v) changing the tuner state to another of said multiple tuner states; (vi) repeating steps (ii), (iii), (iv) and (v) until data has been measured for each of said multiple tuner states, wherein the data is measured as a function of the sweep parameter for said set of parameter values for one tuner state at a time.
