Abstract: A slide screw tuner movement control mechanism uses two horizontal stepper motors driving the ACME lead screw, which controls the horizontal position of the mobile carriage moving the tuning probe along the slabline. Each motor is linked with the ACME using different gear ratio, designed for coarse and fine horizontal increment (step size). This allows making ultra-wideband tuners with Fmax:Fmin>10:1 for optimized tuning speed at low frequencies and high tuning resolution at high frequencies. Appropriate calibration and optimized movement algorithms extract the best compromise between speed and tuning resolution.
