Summary:The article briefly describes the goals and tasks of the planned “Sun–Terahertz” space experiment on board the Russian segment of the ISS. The experiment was aimed at studying radiation from the Sun in the unexplored terahertz range at frequencies of 10 12 –10 13  Hz and obtaining new data on the terahertz radiation of the Sun, solar active regions, and solar flares. The scientific equipment being developed is a set of eight detectors sensitive to radiation of various frequencies: 0.4, 0.7, 1.0, 3.0, 5.0, 7.0, 10.0, and 12.0 THz. The main components of the electronics unit of the scientific equipment are considered: amplifiers, optical-chopper drivers, the power board, and the electronics board. The accuracy of signal measurements using an ADC on the electronics board was calculated, and the sensitivity of the scientific equipment was assessed.
