A Resonant Coaxial Wavemeter line such as illustrated in Fig. 16.1 and operating as a resonant system can be used to measure frequencies in the range of 600 — 10,000 MHz. At lower frequencies the cavity becomes excessively long and at higher frequencies the dimensions become very small.

What does a Wavemeter do?

Wavemeter, device for determining the distance between successive wavefronts of equal phase along an electromagnetic wave. The determination is often made indirectly, by measuring the frequency of the wave.

What is Wavemeter in microwave?

[′mī·krə‚wāv ′wāv‚mēd·ər] (electromagnetism) Any device for measuring the free-space wavelengths (or frequencies) of microwaves; usually made of a cavity resonator whose dimensions can be varied until resonance with the microwaves is achieved.
