Abstract. The waveguide setup and the circuit diagram of a microwave reflectometer consisting of one directional coupler and a resonance waveguide slit PIN diaphragm are presented. The operation of the reflectometer is analyzed. Methods for tuning, calibration and accuracy verification are given. The output readings of the reflectometer are independent of parameter instabilities arising in the units.
