To address the issue of high tolerance in BER performance testing of high-speed demodulator with code rate higher than 300 Mbps,a new method of Eb/N0 testing is proposed. By using the power test function of a spectrometer with settable integral band-width,the signal power and noise power are obtained,and then Eb/N0 is obtained by theoretical calculation. The method reduces the test error as much as possible under the existing test conditions,and improves the accuracy of measurement.
