Paper Abstract

The Spectral and Photometric Imaging Receiver (SPIRE) is one of three scientific instruments onboard the European Space Agency (ESA)'s Herschel Space Observatory. The low to medium resolution spectroscopic capability of SPIRE is provided by an imaging Fourier transformspectrometer of the Mach-Zehnder configuration. Instrument performance of the SPIRE flight model was evaluated during a series of test campaigns. The SPIRE instrument performance verification was completed with instrument delivery to ESA in early 2007. In this paper we present the resulting performance characteristics of the SPIRE spectrometer flight model as determined from these test campaigns. We verify the instrument's conformance with fundamental design specifications such as spectral coverage and resolution. Variations across the imaging array of such properties as spectral resolution, vignetting, and instrumental line shape are explored. Additionally, instrumental artefacts observed during final verification testing are identified and quantified; with explanations provided for potential causes, and proposed methods to minimize their impact on scientific observations described.
