Description

technical field [0001] The invention relates to the technical field of automatic testing, in particular to a board testing device and a testing system. Background technique [0002] The nuclear test system outside the reactor is an important safety-level instrument and control system subsystem of a nuclear power plant. It usually consists of a neutron detector assembly, a preamplifier, and an external nuclear test signal processing system. Among them, the neutron detector assembly is used to collect thermal neutrons leaked from the pressure vessel; the preamplifier is used to amplify and process weak electrical signals; signal from the sub-detector. [0003] In order to ensure the safe and reliable operation of nuclear power plants, functional performance tests are required before the boards of the nuclear test signal processing system outside the reactor are put into use. At present, the board function and performance test of the nuclear test signal processing system outs...
