Measurements are presented on the contributions from dielectronic satellite transitions from upper configurations 1{ital s}2{ital lnl}{prime}, {ital n}{ge}3 to the characteristic x-ray emission of heliumlike Fe{sup 24+}. The measurements were carried out on the electron beam ion trap at Livermore using high-resolution Bragg-crystal spectroscopy. By eliminating uncertainties in the location and magnitude of the satellite contributions inherent in theoretical predictions the measurements improve the use of the resonance line emission of heliumlike Fe{sup 24+} as a diagnostic of ion temperature and rotation velocity of high-temperature plasmas.
