  We report on a 50 ks observation of the bright Seyfert 1 galaxy MCG--6-30-15
with the Rossi X-ray Timing Explorer. The data clearly show the broad
fluorescent iron line (equivalent width ~ 250 eV), and the Compton reflection
continuum at higher energies. A comparison of the iron line and the reflection
continuum has enabled us to constrain reflective fraction and the elemental
abundances in the accretion disk. Temporal studies provide evidence that
spectral variability is due to changes in both the amount of reflection seen
and the properties of the primary X-ray source itself.
