The target level search function is used to locate the marker with the given level of the measured parameter (See figure below).
The trace can have two types of transition at the points where the target level crosses the trace:
•Transition type is positive if the function derivative (trace slope) is positive at the intersection point with the target level.
•Transition type is negative if the function derivative (trace slope) is negative at the intersection point with the target level.
Target level search
Target level search is performed only for intersection points that have a user-selected specific transition polarity (positive, negative, or both).
The following options for the target level search are available:
•search for nearest target
•search for left target
•search for right target
To enable/disable a peak search function, use the softkeys Markers > Search > Search Target on left menu bar. To set the target level value click on the Target Value field and enter the value using the on-screen keypad. To set the transition type click on the Target Transition field. Depending on the search function select one of the following softkeys: •Search Target •Target Left •Target Right

Activate the marker before starting target level search (See Marker Activation). In Smith chart and Polar formats, the search is executed for the first marker value. |
