We will present data acquired by ROSAT's Position Sensitive Proportional Counter for PSR 1509-58. PSR 1509-58 is a young pulsar with dynamical age tau =P/(2 dot P) ~ 1600 yr. MSH 15-52, the supernova remnant in which it is located, has an estimated age of 10(4) years and is at a distance of 4.2 kpc. This environment is similar to that of the Crab Pulsar and Nebula association. PSR 1509-58 has a period of 150 ms, and a period derivative of 1.5 times 10(-12) ss(-1) , the largest period derivative observed for a pulsar. The pulsar also has a large fraction of it's emission in x-rays pulsed. The pulsar was detected with a count rate of ~ 0.23 c/s. The spectrum of the pulsar is hard and power-law like with a photon index of -2.1. The results of pulse phased spectral analysis will be presented and compared to other x-ray pulsars.
