We have used the University of California Lawrence Livermore National Laboratory's EBIT-I electron beam ion trap to perform measurements of the wavelengths and relative intensities of the X-ray lines from inner-shell satellite transitions in sodium-like Fe XVI. The measurements were carried out with high-resolution crystal and grating spectrometers and covered the 14.5-18 A wavelength band. In contrast to some predicted line strengths and positions found in the literature, our results show that the strongest relatively unblended inner-shell satellites of Fe XVI are located near 15.2 A. This is near the location of the 3d{yields} 2p intercombination line in Fe XVII. Calculations using the Flexible Atomic Code (FAC) are presented. The average deviation between the EBIT-I measurements and the FAC calculations for the wavelength positions and line ratios are 22 mA and a factor of 2.3, respectively, where the average is taken over the ten features included in this work.
