Automatic peak search
A peak search can be repeated automatically after each sweep to keep the maximum
value as the reference point for a phase noise measurement. Automatic peak search is
useful to track a drifting source. The delta marker 2, which shows the phase noise
measurement result, keeps the delta frequency value. Therefore, the phase noise
measurement leads to reliable results in a certain offset although the source is drifting.
Using a peak as a fixed reference marker
Some results are analyzed in relation to a peak value, for example a carrier frequency
level. In this case, the maximum level can be determined by an initial peak search and
then be used as a reference point for further measurement results.
