Softkey Functions
Marker Search Menu
Marker Search Menu
Key Operation Function SCPI Command
Displays softkeys for performing searches using markers.
Max
Moves the active marker to a position on the trace that represents
the maximum response value. :CALC{1-16}:MARK{1-10}:FUNC:EXEC
:CALC{1-16}:MARK{1-10}:FUNC:TYPE MAX
Min
Moves the active marker to a position on the trace that represents
the minimum response value. :CALC{1-16}:MARK{1-10}:FUNC:EXEC
:CALC{1-16}:MARK{1-10}:FUNC:TYPE MIN
Peak
Displays softkeys for setting and performing a peak search. A peak refers to a point where the response value is
larger (positive peak) or smaller (negative peak) than those of adjacent measurement points on either side in a
rectangular display format. A peak search picks up points that satisfy definitions given by
Peak Excursion
and
Peak Polarity
among all the peaks. 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 Peak
In the rectangular display format, the active marker will move to
the peak with maximum response value among the peaks that
match the definition if the peak polarity is
Positive
or
Both
, or to
the peak with minimum response value if the peak polarity is
Negative
.The search is performed based on conditions defined by
Peak Excursion
and
Peak Polarity
.
:CALC{1-16}:MARK{1-10}:FUNC:EXEC
:CALC{1-16}:MARK{1-10}:FUNC:TYPE PEAK
Search Left
In a rectangular display format, moves the active marker to the
peak on its left under the given conditions. The search is
performed based on conditions defined by
Peak Excursion
and
Peak Polarity
.
:CALC{1-16}:MARK{1-10}:FUNC:EXEC
:CALC{1-16}:MARK{1-10}:FUNC:TYPE LPE
Search Right
In a rectangular display format, moves the active marker to the
peak on its right under the given conditions. The search is
performed based on conditions defined by
Peak Excursion
and
Peak Polarity
.
:CALC{1-16}:MARK{1-10}:FUNC:EXEC
:CALC{1-16}:MARK{1-10}:FUNC:TYPE RPE
Peak Excursion
Sets the peak offset (and performs
Search Peak
at the same time).
Peak offset is the difference between the response value of a peak
and those of adjacent peaks of opposite polarity (the vertical
interval between the tip and the base of a slope, one each on the
left and right) in a rectangular display format. The smaller of the
two will be used. The peak search will detect peaks with an offset
larger than the set value.
:CALC{1-16}:MARK{1-10}:FUNC:PEXC
Peak Polarity
Displays softkeys for selecting the polarity of peaks. A peak search will detect peaks having the matching
polarity.
Positive
Selects positive polarity (and performs
Search Peak
at the same
time). A positive peak is a point whose measured value is larger
than the values of the two adjacent points on its left and right.
:CALC{1-16}:MARK{1-10}:FUNC:PPOL POS
Negative
Selects negative polarity (and performs
Search Peak
at the same
time). A negative peak is a point whose measured value is smaller
than the values of the two adjacent points on its left and right.
:CALC{1-16}:MARK{1-10}:FUNC:PPOL NEG
Both
Selects both positive and negative polarity (and performs
Search
Peak
at the same time).
:CALC{1-16}:MARK{1-10}:FUNC:PPOL BOTH
Cancel
Returns to the softkey display screen one level higher.
Return
Returns to the softkey display screen one level higher.
