Content

During the preparation and execution of this experiment you will get a basic comprehension of the most important ideas and quantities of a heterodyne radiometer. The setup contains all essential components of a heterodyne detector system as it is widely used in radioastronomy, e.g. inside the 3 m KOSMA radio telescope or any other (millimeter and submillimeter) telescope. Hence, this experiment is thematically closely linked to projects of our institute.
