Procedure
1. Activate the marker you are using to search for the maximum and
minimum values.
2. Press Marker Search key.
3. Click the corresponding softkey to move the marker to the maximum
or minimum measured value.
Searching for the Peak
The peak search function enables you to move the marker to the peak on
the trace.
Definition of the peak
A peak is a measurement point of which the value is greater or smaller
than the adjoining measurement points on its right and left sides. Peaks
are classified into the following two types depending on the differences in
magnitude from the measurement points on either side of it.
Positive peak
(Positive)
A peak of which the measured value is greater than
the measurement points on either side of it (peak
polarity: positive).
Negative peak
(Negative)
A peak of which the measured value is smaller than
the measurement points on either side of it (peak
polarity: negative).
About Peak Excursion Value
The peak excursion value is smaller among the differences in the measured
values from the adjoining peaks of the opposite polarity.
Executing a Peak Search
The following three methods are available for executing the peak search:
Peak search
(Search
Peak)
Moves the marker to the maximum peak when peak
polarity is Positive or Both. Moves the marker to the
minimum peak when peak polarity is Negative.
