Wideband multiprobe microwave multimeter

The device, sensors and mathematics permit us to get new results in precision, performance function linearity, long term stability characteristics and so on. A multimeter, for passing, incident, reflected power, reflection coefficient module, and phase and wavelength, could be designed in the three versions, depending on its purpose: multimeter for fixed frequency; wideband one for waveguide; very wideband one for coaxial lines. It is necessary to solve the next main questions: choice of sensor type and their dislocation; elaboration of the signal processing algorithm; the functional scheme; evaluation of general error; ground metrological support.
