CALCulate:MARKer[1|2|3|4]:MINimum:NEXT
Places the marker on the next lowest pit from the current marker amplitude.
This next lowest pit must meet the pit excursion and threshold criteria. If the
specified marker is
OFF
, it will be turned
ON
, placed at the center wavelength,
and the search for the next minimum will begin from that point.
CALCulate:MARKer[1|2|3|4]:MINimum:RIGHt
Places the marker on the next pit located at a longer wavelength than the cur-
rent marker wavelength position. This next pit must meet the pit excursion
and threshold criteria. If the specified marker is
OFF
, it will be turned
ON
,
placed at the center wavelength, and the search to the right will begin from
that point.
CALCulate:MARKer[1|2|3|4]:PEXCursion[:PEAK] <numeric_value>
CALCulate:MARKer[1|2|3|4]:PEXCursion[:PEAK]?
Sets the peak excursion value for the marker search routines. The peak excur-
sion value is used to determine whether or not a local maximum in the trace is
to be considered a peak. To qualify as a peak, both sides of the local maximum
must fall by at least the peak excursion value.
CALCulate:MARKer[1|2|3|4]:PEXCursion:PIT <numeric_value>
CALCulate:MARKer[1|2|3|4]:PEXCursion:PIT?
Sets the pit excursion value for the marker search routines. The pit excursion
value is used to determine whether or not a local minimum in the trace is to be
considered a pit. To qualify as a pit, both sides of the local minimum must rise
by at least the pit excursion value.
CALCulate:MARKer[1|2|3|4]:SCENter
Sets the center wavelength to the wavelength value of the marker.
CALCulate:MARKer:SRANge:LOWer?
Returns the lower limit for the marker search range. The range used for the
marker search range is the same range used for the total power calculation,
the trace mean range, and the wavelength sweep range. The return value is in
meters, unless span is set to zero, in which case the return value is in seconds.
