An impedance tuner system, usable in a measurement system including at least one measurement system device, the tuner system comprising the impedance tuner having a signal transmission line, and an impedance-varying system coupled to the transmission line, and responsive to command signals to selectively vary the impedance presented by the impedance tuner. An impedance tuner controller is configured to generate the command signals, and wherein measurement device drivers and at least one of characterization, calibration and measurement algorithms are embedded into the tuner controller, the tuner controller configured to allow a user to control execution of said at least one of the characterization, calibration and measurement algorithms using the tuner controller.
