BS EN 61580-8 is an international standard that provides the methods of measurement for waveguides.
BS EN 61580-8 describes the measurement of the power holding of a waveguide using a multiplying loop. In this case, the input power required is much less (– 10 dB to – 12 dB) than when the WUT is directly connected to a high-power source. Loop power is measured via coupler PS, and reverse power via PR.
BS EN 61580-8 on waveguide power holding capability is relevant to:
A waveguide is an electromagnetic feed line used in microwave communications, broadcasting, and radar installations.
BS EN 61580-8 gives you a methodology to measure the power holding capability for waveguides. It gives you detailed information about the test equipment needed to perform the test, explains the principle of the test, and helps the users to execute the calculations and test procedure for checking power holding capability.
