Abstract: Multi-band remotely configurable tuning probes for slide screw impedance tuners allow instantaneous larger frequency coverage beyond the capacity of existing tuning probes using the single horizontal and vertical axis mechanism of a prior art single probe, single band tuner. This is done by carving multiple slugs of different length and frequency coverage as segments of a disc-shaped revolving slab, which rotates inside the legs of a captive unit and locks at distinct angles. The captive unit is attached to the vertical control mechanism of the tuner and rotation is ensured using multiple traverse lateral studs on the disc unit and a set of vertical studs on the slabline close to the idle port of the tuner. An automated procedure ensures remote switching between tuning slugs. Calibration and tuning is as in prior art single probe tuners.
