DEVELOPMENT OF STANDARD CALIBRATION PROCEDURE FOR INTERFERENCE MEASURING INSTRUMENTS.
Abstract
This report describes the work performed (1) to develop a standard procedure for calibration of Navy interference measuring equipments from 14 kc. to 1000 mc., and (2) to furnish a working model of an instrument capable of performing the standard calibrations. A procedure has been developed for the calibration of interference measuring equipments from 100 microvolts to 100 mv. rms, over the frequency range from 14 kc. to 1000 mc. The procedure employs a d.c. thermistor bridge in conjunction with a coaxial attenuation circuit. A working model of such a calibration instrument has been designed, constructed, and tested. This report presents detailed discussion concerning the design and theory of operation of the calibration instrument. The discussion is supplemented by pertinent drawings, photographs, schematic diagrams, and theoretical and experimental curves. Pertaining to the utilizaton and construction of the RF calibration instrument, the report includes: (1) Complete, concise instructions for the effective operation of the instrument in performing the calibration of Navy interference measuring instruments; (2) Photographs and sketches showing the constructon of components, and the assemblage of parts and materials into a working model; and (3) Lists of parts required for the construction of the calibration instrument and ancilliary equipments required for the calibration procedure.
