We report the first measurements of anisotropy in the cosmic microwave background (CMB) radiation with the Arcminute Cosmology Bolometer Array Receiver (ACBAR). The instrument was installed on the 2.1\,m Viper telescope at the South Pole in December 2000; the data presented here are the product of observations up to and including July 2002.

The large 3 degree extent of the maps, and small beamsize of the experiment allow the measurement of the CMB anisotropy power spectrum over the range \ell = 150-3000 with resolution of \Delta \ell=150. We discuss the observation strategy, analysis method, and the cosmological implication of the results.
