Abstract : Blazars are subclass of active galaxies, where the relativistic jet makes very small angle with line of sight of the observer. Hence these are the best sources to understand the physics of emission process in the jet. They are bright in gamma-rays and show high variability throughout the electromagnetic spectrum. Construction of Spectral Energy Distribution (SED) during both high and low activity states in different time period from the observed data and associated theoretical modeling is essential to identify jet parameters responsible for such different activity states. PKS 0208-512 is one of the Fermi detected EGRET blazars that exhibits long term low gamma-ray activity state. Here, we present the preliminary results of our detailed study of blazar PKS 0208-512 utilizing observations from FERMI-LAT, SWIFT-XRT, SMARTS and recent observations from ASTROSAT.
