Systems and methods for adjusting power and frequency based on three or more states are described. One of the methods includes receiving a pulsed signal having multiple states. The pulsed signal is received by multiple radio frequency (RF) generators. When the pulsed signal having a first state is received, an RF signal having a pre-set power level is generated by a first RF generator and an RF signal having a pre-set power level is generated by a second RF generator. Moreover, when the pulsed signal having a second state is received, RF signals having pre-set power levels are generated by the first and second RF generators. Furthermore, when the pulsed signal having a third state is received, RF signals having pre-set power levels are generated by the first and second RF generators.

A method of processing a plurality of received digitized signals may include determining a plurality of cross-correlation coefficients for the plurality of received digitized signals; forming a cross-correlation coefficient vector including the plurality of cross-correlation coefficients; and determining an evaluation value for at least some of the plurality of cross-correlation coefficients. The determining the evaluation value may include: pre-selecting a predefined number of cross-correlation coefficients from the cross-correlation coefficient vector and deleting the pre-selected number of cross-correlation coefficients from the cross-correlation coefficient vector; after the pre-selection, determining an averaging value using at least one of the non-preselected cross-correlation coefficients of the cross-correlation coefficient vector; and determining the evaluation values based on the respective value of the pre-selected cross-correlation coefficient and the averaging value. The method may further include selecting one or more cross-correlation coefficients based on the determined evaluation values; and further processing based on the selected one or more cross-correlation coefficients.

A new multi-carriage slide screw impedance tuner uses a circular slabline, eccentrically rotating disc probes and rotating carriages allowing reducing the linear size of the tuner by a factor of 3 compared with linear tuners. The slabline lies flat on the bench table surface and the disc probes rotate at the end of rotating arms, which act as mobile carriages, forming a planetary configuration. The rotation of the arms control the phase of GAMMA and the rotation of the disc-probes controls its amplitude.
