Target
Displays softkeys for setting and performing target searches. A target refers to a point on a trace that has a unique
response value (target value) in a rectangular display format. A target search picks up points that have matching
characteristics defined by
Target Value
and
Target Transition
. If the Smith chart format or polar format is used, the
main response value, among the two response values, will be used to perform searches (e.g., resistance in the
Smith (R+jX)
format).
Search Target
In a rectangular display format, moves the active marker to the
nearest target (i.e., the closest stimulus value on the X-axis) that
matches the definition (having a unique response value - the target
value). The conditions for a target search must be defined using
Target Value
and
Target Transition
.

:CALC{1-16}:MARK{1-10}:FUNC:TYPE TARG
Search Left
In a rectangular display format, moves the active marker to the
target that is nearest on its left and that matches the definition
(having a unique response value - the target value). The
conditions for a target search must be defined using
Target Value
and
Target Transition
.
:CALC{1-16}:MARK{1-10}:FUNC:EXEC
:CALC{1-16}:MARK{1-10}:FUNC:TYPE LTAR
Search Right
In a rectangular display format, moves the active marker to the
target that is nearest on its right and that matches the definition
(having a unique response value - the target value). The
conditions for a target search must be defined using
Target Value
and
Target Transition
.
:CALC{1-16}:MARK{1-10}:FUNC:EXEC
:CALC{1-16}:MARK{1-10}:FUNC:TYPE RTAR
Target Value
Sets the target value (desired response value). (Also performs
Search Target
at the same time.) A target search uses the target
value to look for a point on a trace.
:CALC{1-16}:MARK{1-10}:FUNC:TARG
Target Transition
Displays softkeys for defining the transition direction.
Positive
Selects positive transition for a target search (and performs
Search
Target
at the same time). Targets with positive transition refer to
points whose response value is larger than the value of the
adjacent point on its left in a rectangular display format.
:CALC{1-16}:MARK{1-10}:FUNC:TTR POS
Negative
Selects negative transition for a target search (and performs
Search Target
at the same time). Targets with negative transition
refer to points whose response value is larger than the value of the
adjacent point on its left in a rectangular display format.
:CALC{1-16}:MARK{1-10}:FUNC:TTR NEG
Both
Selects both positive and negative transition for a target search
(and performs
Search Target
at the same time).
:CALC{1-16}:MARK{1-10}:FUNC:TTR BOTH
Cancel
Returns to the softkey display screen one level higher.
Return
Returns to the softkey display screen one level higher.
Tracking
Enables or disables search tracking. When enabled, the currently
selected search operation will be performed each time a sweep is
completed. If disabled, you can initiate a search by pressing a key
for a particular search. :CALC{1-16}:MARK{1-10}:FUNC:TRAC
Search Range
Displays softkeys for setting the search range of the maximum, minimum, peak and target search.
Search Range
Enables or disables partial search feature. :CALC{1-16}:MARK:FUNC:DOM
Start
Sets start value (lower limit) of the search range. :CALC{1-16}:MARK:FUNC:DOM:STAR
Stop
Sets stop value (upper limit) of the search range. :CALC{1-16}:MARK:FUNC:DOM:STOP
Couple
Enables or disables trace coupling within search range. :CALC{1-16}:MARK:FUNC:DOM:COUP
Return
Returns to the softkey display screen one level higher.
