We present the design and testing of a submillimeter spectrometer based on a helium-cooled scanning Fabry-Perot and superconducting transition edge sensor bolometers. The Fabry-Perot uses a low resolution grating to order sort the incoming light. A linear bolometer array consisting of 16 elements detects this dispersed light, capturing 5 orders simultaneously from one position on the sky. With tuning of the Fabry-Perot over one free spectral range, a spectrum covering \Delta\lambda/\lambda=1/7 at a resolution of \delta\lambda/\lambda~/1500 can be acquired. Made for operation in the 350\mum and 450\mum bands, this spectrometer will be used at the Caltech Submillimeter Observatory in 2001.
