Characterization of the Advanced Photon Source storage ring particle beams includes transverse and longitudinal profile measurements using synchrotron radiation-based techniques. Both optical (OSR) and x-ray synchrotron radiation stations are now installed. Spatial resolution of about {sigma}=55{mu}m was obtained at low current in the visible field initially. This is expected to improve during commissioning. UV/visible light from the storage ring bending magnet was used to measure the particle beam with a resolution of {sigma}{approximately}80{mu}m and allow operation at 100 mA with the initial x-ray pinhole setup. Early OSR measurements of beam size are consistent with 8.2 nm-rad emittance and 2-3% vertical coupling. Early results with the x-ray pinhole camera are also presented.
