The present disclosure provides a multi-parameter calibration system for a spectrometer based on a nanosecond light source, including a main channel for outputting nuclear pulse signals, and a coincidence channel for outputting the nuclear pulse signals. Each channel uses current nuclear pulse signals to drive a light-emitting diode (LED) to emit nuclear pulse optical signals, and a simulated scintillator is irradiated to emit nanosecond nuclear pulse optical signals. The present disclosure can respectively test and calibrate multiple parameter performance indexes of the spectrometer throughput baseline restoration spectrometer. The stability of the spectrometer is tested and calibrated through output of certain regular nuclear pulse signals.
