The Heterodyne Instrument for FIRST (HIFI) will cover at least the frequency range 492 GHz to 1113 GHz and will provide sensitive observations with resolving powers ranging from less than 5x105 to 1.2x107. The instrument is optimised for the measurement of weak, broad spectral lines of distant galaxies and for performing fast line surveys of galactic objects. This paper describes the performance, observing modes, and calibration modes of the planned instrument. Companion papers in these Proceedings describe the instrument optics, mixers and spectrometer systems.

In the Proceedings of 'The Far InfraRed and Submillimetre Universe', an ESA symposium, held 15-17 April 1997 in Grenoble, France.
