Microwave frequency measurement is done by slotted line, resonant cavities and transfer oscillator.
Microwave power measurement uses bolometers and microwave power meters.
A self balancing bridge working on the principle of power substitution is commonly used.
Microwave impedance measurement is done by measurement of reflection coefficient and VSWR.
A slotted line and probe is a basic tool for these measurements.' Network analyser enables rapid impedance measurement over a broad frequency range.
