Abstract :
The reflection coefficient measurement error for a three-probe reflectometer was analyzed. The influence of power measurement error, probe location, reference coupler directivity, attenuator value and probe coupling on the reflectometer´s useful frequency bandwidth was investigated using computer simulation. The useful frequency bandwidth for the reflectometer with commonly used parameters, was estimated.
