The microchannel-plate photomultiplier tube (MCP-PMT) is the key component in the Daya Bay reactor neutrino experiment II. However, there are few approaches to evaluate its properties. Based on the situation, a testing system and a series of experiments to assess the static performance of MCP-PMT have been developed. The MCP-PMT with 8 inch diameter applied with high voltage is illuminated by appropriate incident light. The cathode and anode current are sampled by capture card to calculate
