We present the results from simultaneous chandra and rxte observations of theX-ray bright Broad-Line Radio Galaxy (BLRG) 3C 382. The long (120 ks) exposurewith chandra HETG allows a detailed study of the soft X-ray continuum and ofthe narrow component of the Fe Kalpha line. The rxte PCA data are used to putan upper limit on the broad line component and constrain the hard X-raycontinuum. A strong soft excess below 1 keV is observed in the time-averagedHETG spectrum, which can be parameterized with a steep power law or a thermalmodel. The flux variability at low energies indicates that the origin of thesoft excess cannot be entirely ascribed to the circumnuclear diffuse emission,detected by chandra on scales of 20-30 arcsec (22-33 kpc). A narrow (sigma<90eV) Fe Kalpha line (with EW< 100 eV) is observed by the chandra HEG. Similarvalues for the line parameters are measured by the rxte PCA, suggesting thatthe contribution from a broad line component is negligible. The fact that theexposure is split into two observations taken three days apart allows us toinvestigate the spectral and temporal evolution of the source on differenttimescales. Significant flux variability associated with spectral changes isobserved on timescales of hours and days. The spectral variability is similarto that observed in radio-quiet AGN ruling out a jet-dominated origin of theX-rays.
