Description: RXTE was the workhorse in the field of rapid time variability during 1996-2012. Now, LAXPC instrument onboard AstroSat effectively replace RXTE and contributing to the rapid variability studies in the 3 80 keV energy band. The large effective area and superior time resolution make the LAXPC an ideal instrument to explore the timing properties of XRBs in the hard X-ray band.
