  The high energy experiment PDS is one of the Narrow Field Instruments aboard
the X-ray astronomy satellite BeppoSAX. It covers the energy band from 15 to
300 keV. Here we report results on its in-flight performance and observations
of galactic and extragalactic X-ray sources obtained during the Science
Verification Phase of the satellite: in particular Crab, Cen X-3, 4U1626-67 and
PKS2155-305.
