Techniques involved in the spectroscopy of pulsed plasma sources in the vacuum ultraviolet and soft x-ray spectral regions are described in connection with recent developments in a high temperature plasma physics program. The time-integrated spectrum between 15 Å and 1800 Å has been analyzed using semiautomatic computer techniques for the grazing incidence portion. Time resolved absolute intensity measurements of 0 iii- O viii ion lines are described as related to recent results on energy losses and impurity content, as well as excitation rate coefficients. Broadband measurements of x-ray continuum radiation with four simultaneous detection channels are also described, and typical results of computer calculations necessary for the interpretation in terms of electron temperature are included.
