A survey of selected developments in microwave phase measurement techniques is presented. General characteristics such as precision, accuracy, and versatility are compared briefly. Particular attention is given to errors inherent in the different tec

The treatment of mismatch errors is extended to cover variable attenuators cascade-connected in a system which is not free from reflections. The method of analysis is applicable to any number of cascaded attenuators, but only the analysis of two and

A systems concept of the measurement activities in the United States is briefly reviewed. This concept is the one recently proposed (1966) by R. D. Huntoon and named the "National Mesurement System" by him. His description of the role of the Institut

The phase difference between the incident and transmitted waves at the input and output ports, respectively, of a two-arm waveguide junction in a reflection free system is a characteristic of the waveguide junction and is defined as the "phase shift.

A method of measuring microwave attenuation is proposed which has the advantages of an i.f. substitution method with single-sideband operation. However, ordinary amplitude modulation is used, and neither the carrier nor one of the sidebands needs to

A method is described for producing an amplitude modulated wave at an intermediate frequency from the mixing of two cw signals in a coaxial or waveguide system. The method is adaptable to any frequency range in which crystal mixers are used. At least
