Gets the start frequency of the 2nd best-fit linear least square regression line measured over user specified sample analysis time interval as determined by Pulse Freq Phase Dev Range Length (%) method for the measured pulses. This value is expressed in Hz. This result is valid only for triangular FM modulation.
