Heterodyne instrumentation at the CSO
TL;DR: The Caltech Submillimeter observatory (CSO) is one of the World's premier submillimeter telescopes as discussed by the authors. But it is not suitable for the study of highly red-shifted extra-galactic sources.

TL;DR: Balanced receivers are used at the Caltech Submillimeter Observatory (CSO) for the 230/460 GHz and 345/660 GHz atmospheric windows as discussed by the authors, where they provide a high level of amplitude noise immunity and allow all of the available LO power to be used.
