The calibration is by noise injection, with a choice between two levels. This receiver uses a cooled, HFET amplifier. It has one beam with dual polarizations. The feed is a corrugated horn with cooled OMT producing linear polarizations. The user can select circular polarization synthesized using a hybrid in the front-end.
