The TRISTAN detector is an upgrade to the KATRIN experiment to enable a differential measurement of the tritium β-decay spectrum to search for the experimental signature of keV scale sterile neutrinos. The TRISTAN detector upgrade consists of performing precision electron spectroscopy with over 1000 silicon drift detector pixels, each responsible for recording event rates of 105 counts per second. A project specific data acquisition (DAQ) system is developed to meet the experimental challenges with a remote analog to digital conversion (RADC) design. In this work, the conceptual design of the RADC DAQ is presented along with the built system for operating the TRISTAN detector upgrade. The system includes flexible signal processing logic and data management that is optimized for the high-rate precision measurement.
