An impedance tuner is an apparatus, which generates controllable reflection factor (Impedance) over a certain frequency range. Focus uses two basic technologies:

Focus provides the deepest portfolio of wideband fundamental and harmonic passive tuners. Passive impedance tuners generate controllable reflection factor (Impedance) across the smith chart over a given frequency range. Focus uses two basic technologies: From 100MHz to 120GHz we use the slide screw technique in which a reflective probe is inserted into a low loss slotted transmission line.

3 Measurement States; Quiescent (OFF-State), Non Quiescent (ON-State), and Pre-State The Pre State is a short high voltage state used to activate
