Mark frequency point.
(b2) if the signal strength for the frequency point that current search arrives is more than the intensity threshold of setting, the frequency that current search is arrived
Point is used as target frequency point.
For example, when being scanned for successively to the frequency point in the preferential frequency point list of rate, when the signal of the frequency point B searched
Intensity -70dB is more than preset intensity threshold -75dB, then directly using frequency point B as target frequency point, follow-up frequency point is searched in stopping
