Abstract:
A tool for tuning a cavity filter, the tool comprising:a shaft assembly having a tip, the tip adapted to selectively engage tuning members in plates of cavity filters to adjust and monitor the position of tuning members; a positional measuring unit, responsive to the shaft, that is adopted to determine positional data for a tuning member; a data base for storing positional data of a reference tuning member in a tuned filter; a controller, coupled to the data base, the positional measuring unit and the shaft assembly; wherein the controller determines the position of the reference tuning member in the tuned filter based on measurements from the positional measuring unit for storage in the data base; and wherein the controller controls the position of tuning members in an un-tuned filter based on positional data in the data base using the shaft assembly.
