An electro-mechanical microwave impedance tuner operates as a stand-alone instrument and includes on-board digital processor, firmware, memory, digital display and human control interface, in form of a joystick, mouse, keyboard or tactile (touch sensitive) screen in order to recognize and execute commands for moving the tuner motors and probes, generating required microwaves impedances and calculating losses and de-embedding to reference planes different than the tuner ports. Before being used in operations the tuner can also be controlled by a control computer in order to be calibrated on a network analyzer and the data can be uploaded into the on-board memory in order to be used in the above calculations. During measurement and tuning operations the tuner is therefore stand-alone and totally independent of a control computer.
