Analyzing Data
Searching for Positions That Match Specified Criteria
Defining a Peak
You can define a peak by specifying the lower limit for the peak excursion value and
polarity (positive or negative peak). The peak excursion value is the difference between the
positive peak and the minimum value on either side (or between the negative peak and the
maximum value on either side). For more information about the peak excursion value, see
User’s Guide.
To define a peak, use the following command:
Defining a Target
You can define a target by specifying the target value (response value) and transitional
direction (positive or negative value change).
To define a target, use the following command:
Performing Marker Search
To perform Marker Search, use the following command:
• :CALC{1-4}:MARK{1-10}:FUNC:EXEC on page 268
To turn on or off the Search Tracking feature, which performs Marker Search every time
the trace is updated, use the following command:
• :CALC{1-4}:MARK{1-10}:FUNC:TRAC on page 272
Retrieving Search Results
Performing Marker Search moves the marker to the points that matches the search criteria,
so you can obtain the search results by retrieving the marker value. For information on how
to retrieve marker values, refer to “Setting (Changing) and Retrieving Stimulus Value at
Marker Positions” on page 90 and “Retrieving Measurement Results at Marker Positions”
on page 90.
