ADVANCES IN MICROWAVE ERROR CORRECTION TECHNIQUES Doug Rytting Network Measurements Division 1400 Fountaingrove Parkway Santa Rosa, California 95401 RF &Microwave Measurement Symposium and Exhibition Fli;' HEWLETT ~~ PACKARD www.HPARCHIVE.com www.HPARCHIVE.com ABSTRACT Many improvements have occurred in microwave error correction techniques the past few years. The various error sources which degrade calibration accuracy is better understood. Standards have been developed with increased accuracy and utility. New Calibration techniques have been implemented that offer improved performance with more accurate and easier to manufacture standards. These new techniques also make in-circuit calibrations more practical and traceable. Methods have also been developed to determine the post
