The main goal of the NOvA experiment is to study oscillation parameters in the neutrino and antineutrino beams: measurements of the mass hierarchy and CP-violation phase in the lepton sector. Two identical highly-segmented detectors based on PVC-tubes filled with a liquid scintillator to detect signals from muon and electron neutrinos were built. Masses of each are 300 and 1400 tons. Avalanche PhotoDiode is a core element of the detectors to measure signal response. Total amount in the large Far Detector is 344064. The NOvA test bench was made at JINR for studying native NOvA electronic responses through APD and FEB chain. The bench was used to perform investigations for physical signals in the detectors also. In this work we are presenting the NOvA-JINR bench results which show signal shaping studies, simulation of the electronic response on hypothetical magnetic monopole’s signals and other required to do simulations and precise measurements of the events’ energy.
