The purpose of the invention is to expand the frequency range and simplify the measurement process.

The method for determining the hot I – o K of the standing water stress (VSWR) factor is implemented as follows.

Install the ferrite sensor into the transmission line} ia to the input of the microwave device to be removed; include the microwave amplifier under investigation and, in I pc -: - the buoy mode of operation measures two
