RE: Reference frequency error; MF: Marker frequency [Hz]
The first term of these formula shows the frequency uncertainty due to the reference
frequency error. The second term shows the uncertainty due to the limited bin number.
Because more than 500 bins are available in the frequency display, 0.5 bin uncertainty
corresponds to 0.001. The third term shows the residual FM.
