Abstract
The problem of ensuring the uniformity of measurements of the power of electromagnetic oscillations in waveguide paths,which is relevant in the development, maintenance and operation of electronic equipment, is considered. It is proposed to increasethe transmission accuracy by reducing the refl ection coeffi cient of the input of the terminal type power meters and reducing the mismatch error. A multi-probe end-type converter has been developed, which is part of a waveguide thermistor wattmeter. The prototypes of waveguide thermistor power meters withmulti-probe converters in the frequency range 16.7–37.5 GHz have been manufactured and experimentally investigated. It is shown that this wattmetercan be used as a portable and secondary standards for transmitting the size of a unit of power of electromagnetic oscillations or as an initial measuringinstrument as part of working standards, and also used to control the stability of the eff ective refl ection coeffi cient of the output of a pass-through power meter.
