Resonant cavities have been used to measure the frequency and check the performance of radar transmitters. The object of this paper is to describe the factors influencing the design of such cavities to cover frequency bands near 3000 Mc/s, and to estimate their accuracy in the measurement of both the mean frequency of the transmitter output and its spectral distribution about the mean. The principles described are of general application to the design and use of cavity wavemeters of high discrimination.
