2FSK deviation

[Val]

Hello! I did the measurement of FSK deviation signal and the result was 50kHz, however, when I measure distance between carrier frequency (Fc) and frequency of “1” and “0” (in single tone mode using function of Max Hold), I have a deviation 45kHz. Why I have a difference between these measurements?
The modulation index is 0.9. Does it mean that the actual deviation of my signal will be measured deviation of modulated signal multiplied by 0.9 (modulation index)?
