-For MCP delay line TDC - MCP sensor TDC, if I connected exact same length of cables and same electronics processor after both delayline terminal and mcp sensor signal feeder, the timing of reaching the signal which comes from delay line to TDC should be later than the timing of reaching the signal which comes from MCP sensor.
-But If I select event which only detected one signal on each end of delayline and mcp sensor, the difference between the timing of MCP signal and delay line signal varied between negative number to positive number.
