Searching for the Multiple Target Values (Multi Target Search)
The multi-target search function enables you to display a marker on each
point having the target measurement value.
Target and Transition Types
A target is a point that has a specific measurement value on the trace.
Targets can be divided into two groups shown below depending on their
transition type.
Positive
When the value of the target is larger than the
measurement value that immediately proceeds it (on the
left side).
Negative
When the value of the target is smaller than the
measurement value that immediately proceeds it (on the
left side).

About the multi-target search function (Search Multi Target)
The multi-target search is a function that searches for targets that match
to pre-defined target value and transition type(s) (positive, negative, or
both of positive and negative) and displays markers on the targets being
searched.
Depending on the number of detected targets, markers 1 through 9 are
displayed from the start frequency.
When the multi-target search is executed, search and
tracking settings for markers 1 through 9 are ignored and the
settings for the multi-target search are used. Note that the reference
marker is not affected.
Multi-target Search (when transition type is set to "both positive
and negative")
