| Abstract: | The carrier-to-first-sideband ratio(CFSR) for the measurement of percentage modulation and frequency deviation using spectrum analyzer was studied in this paper.The principle,error,applicable range and relative uncertainty of CFSR were discussed.The frequency-modulated spectrum substitution(FMSS) used for large frequency deviation was discussed. |
