Because the gain spectrum of an Erbium doped fiber amplifier (EDFA) varies with the saturation level
an iterative method of measurement on multichannel gain spectrum under equivalent saturation by using dual wavelength or broadband signal is introduced and the power of the equivalent saturation signal is derived.Only several iterations are required to reach enough accuracy.The error of the experiment is no greater than 0.15 dB.
