Abstract :
The paper describes the comparison of coaxial power-measuring standards developed in the United Kingdom with transfer standards from the United States and Japan, at 300 and 400 Mc/s. The average difference between the US and UK values was 0.2%; and that between the Japanese and UK values was 2.1%. The differences are less than the combined limits of error claimed for the instruments being compared; the limits being (a) US transfer standard: ±0.5%, (b) Japanese transfer standard: ±1.4%, (c) UK standards: ±1% (up to 400mW), ±2.3% (up to 10W).
