We present a measurement of the angular power spectrum of the cosmic microwave background (CMB) using data from the South Pole Telescope (SPT), a 10-meter aperture, mm-wave telescope located at the geographic South Pole. We describe the instrument, the data reduction, and the power spectrum analysis. We present preliminary constraints on cosmological parameters using this power spectrum. We find that the data are consistent with a flat LambdaCDM cosmology and improve the constraints on the standard cosmological parameters. We find evidence for gravitational lensing of the CMB and provide strong constraints on excursions from this standard cosmological model.
