CALCulate Subsystem Commands
CALCulate:MARKer:SRANge[:STATe] OFF|ON|0|1
CALCulate:MARKer:SRANge[:STATe]?
Turns the search range
ON
or
OFF
for all the markers. When the search range is
ON
, all the marker maximum/minimum searches will be within the upper and
lower wavelength range. Although there is a single range controlling the total
power integration, the marker search range, the mean calculation, and the
wavelength sweep range, there are four independent state settings for limiting
the total power integration, the marker search, the mean calculation, and the
wavelength sweep to the range. If all four states for the total power integra-
tion, the marker search, the mean calculation, and the wavelength sweep
range are
OFF
, setting CALCulate:MARKer:SRANge:STATe to
ON
will initialize
the lower range to and the upper range to .
CALCulate:MARKer:SRANge:UPPer?
Returns the upper 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.
CALCulate:MARKer:SRANge:UPPer:FREQuency <param>
Sets the upper limit for the marker search range. Setting this value when
CALCulate:MARKer:SRANge:STATe is
OFF
will automatically turn
CALCulate:MARKer:SRANge:STATe
ON
. 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. Changing the range with this com-
mand will change all four ranges. Sending the command when the instrument
is in a zero span will generate a “Settings conflict” error. The default units for
the parameter is in Hertz.
