Conclusions
-
1.
The random error incurred in measuring frequency deviations by means of the method of reducing to zero the carrier-frequency spectral component and using a spectral analyzer and rectangular modulating signals does not exceed tenths of one percent and decreases with a rising zero-order number in inverse proportion to the square of the ratio Β.
-
2.
The precision in measuring frequency deviations by means of the above method for a constant spectral component value reduced to a nominal zero can be almost three times higher than in measuring deviations by means of the Bessel function zeros.
-
3.
It is advisable to use the method of reducing the spectral component to its nominal zero and using rectangular modulating signals in calibration operations and in determining the additional errors of the frequency-deviation working meters.
