Modern digital crosscorrelators permit the simultaneous measurement of allfour Stokes parameters. However, the results must be calibrated to correct forthe polarization transfer function of the receiving system. The transferfunction for any device can be expressed by its Mueller matrix. We express thematrix elements in terms of fundamental system parameters that describe thevoltage transfer functions (known as the Jones matrix) of the various systemdevices in physical terms and thus provide a means for comparing withengineering calculations and investigating the effects of design changes. Wedescribe how to determine these parameters with astronomical observations. Weillustrate the method by applying it to some of the receivers at the AreciboObservatory.Comment: 23 pages, 2 figures; accepted for PAS
