Abstract : We present results from timing and spectral analysis of a LAXPC observation of the young rotation powered pulsar PSR 1509-58. This is among the sources with highest spin-down energy powering a bright Pulsar Wind Nebula. With a short observation carried out over 8 orbits of Astrosat during 01-02 March 2016, the pulsations have been detected in the entire energy band of 3-80 keV in each of the three LAXPC detectors. We have also accurately measured the spectral parameters of the pulsed emission in the 4-60 keV band. The background variation is mitigated by subtracting the off-pulse component. Prospects for further timing and spectroscopic studies of rotation powered pulsars will also be discussed.
