The Rossi X-ray Timing Explorer (RXTE) observed three active galaxies during its In Orbit Checkout program. They were NGC 4151, NGC 4945, and MCG 8-11-11. All three were detected from 2 keV to greater than 100 keV by a combination of the Proportional Counter Array (PCA) and the High Energy X-ray Timing Experiment (HEXTE), which are coaligned and have identical 1o passively collimated fields of view. The PCA contains five xenon/methane, multilayer, multiwire, gas proportional counters that cover the 2-60 keV range, and the HEXTE is an array of eight NaI/CsI phoswich scintillation counters that cover the 15-250 keV range. The three active galaxies represent the classes of Seyfert 1, Seyfert 2, and intermediate Seyfert, and the results of fitting their spectra to various models containing partial covering fractions, Compton reflection components, and high energy spectral breaks will be discussed.
