Claim:
1. An automated slide screw impedance tuner, comprising a test port and an idle port and two circular slablines 1 and 2, stacked above each-other in a sandwich (double-decker) configuration, separated by spacer discs, whereby the beginning of slabline 1 is associated with the test port and the end of slabline 2 is associated with the idle port, and spiral formed continuous center conductor of the slablines traversing vertically from the end of slabline 1 to the beginning of slabline 2, and at least two mobile carriages, one for each slabline, whereby the carriages have the form of radial arms and are rotated, using stepper motors, around the center of the circular slablines, and whereby each arm-carriage carries at its peripheral end a disc-formed reflective probe, which it moves along the periphery of the associated slabline; whereby the probe self-rotates eccentrically, driven by a stepper motor mounted at the peripheral end of the arm-carriage and is hereby penetrating into the slot of the associated slabline at adjustable distance from the center conductor, whereby the whole mechanism forms a planetary movement of the probes around the center of the slablines.
