ABSTRACT:
An external motor is coupled to a tuning rod extending into a resonant cavity of a transmitter combiner. A microprocessor tuning control system generates motor control signals that cause the motor to rotate the tuning rod, varying the resonant frequency of the cavity so as to minimize the reflected power from the cavity. Incident and reflected power are detected by diodes in the transmitter cable connecter of the cavity. The standing wave ratio is computed and composed with a threshold value to determine if the cavity needs to be retuned. The microprocessor effectuates reading of digital numbers representing the incident and reflected power and makes a "best effort" attempt to tune the resonant frequency of the cavity to the transmitter frequency, using the motor to rotate the tuning rod.
