Abstract : Copious emission at all observed frequencies is a hallmark of accreting supermassive black holes (SMBH). Multi-frequency measurements are therefore critical to understand the observed range in their properties. The spectral energy distributions from radio to X-ray frequencies include the contribution from multiple emission mechanisms and contain imprints of the kinetic power of the jets launched by the accreting black hole, and the Eddington rate of the accretion. Discerning the mix of emission mechanisms is key to understanding the physics of these accreting systems. While such a decomposition requires robust SEDs, which in turn requires quasi-simultaneous measurements, measurements such as those from ASTROSAT which has simultaneous multi-wavelength capability, though sparse, can anchor the SEDs. Our results from two representative accreting SMBH observed with ASTROSAT with the instruments LAXPC, SXT and UVIT will be presented.
