Microwave Measurements and Test Equipments

The techniques used in the measurement of electrical quantities in the microwave region of the spectrum differ considerably from those employed at lower frequencies; indeed, the quantities which it is desired to measure are often fundamentally different. A brief summary of some of the more important measurement methods is given and the electrical and mechanical considerations in the design of microwave measurement apparatus are discussed. Accuracies obtainable with the present state of the art are given. Application to measurement of radar systems is treated briefly.
