We discuss characterization and some astronomical results of the Zpectrometer, a new instrument on NRAO's 100 meter diameter Green Bank Telescope. The Zpectrometer is designed for use with the Ka band receiver, providing 12.1 GHz of instantaneous bandwidth (26.5 to 37.7 GHz). With excellent stability and the GBT's large collecting area, this correlation spectrometer is able to observe the CO(1-0) transition in galaxies at redshifts 2.06 < z < 3.5, as well as other lines. We discuss the design of key hardware elements of the system and present astronomical results from observations with the Zpectrometer, including the Cloverleaf Galaxy at z = 2.56.
