SENSe Subsystem Commands
[SENSe:][WAVelength:]SPAN <numeric_value>[M|NM|UM|A]
[SENSe:][WAVelength:]SPAN?
Specifies the wavelength span. The start and stop wavelength and, if neces-
sary, the center wavelength are adjusted so that:
and
[SENSe:][WAVelength:]SPAN:FULL
Sets the wavelength span of the spectrum analyzer to full span.
[SENSe:][WAVelength:]SRANge:LOWer <numeric_value>[M|NM|UM|A|HZ|KHZ|MHZ|GHZ]
[SENSe:][WAVelength:]SRANge:LOWer?
Sets the lower limit for the wavelength sweep range. Setting this value when
SENSe:WAVelength:SRANge:STATe is
OFF
will automatically turn
SENSe:WAVelength:SRANge:STATe
ON
. The range used for the wavelength
sweep range is the same range used for the total power integration, the trace
mean range, and the marker search 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.
Default units for the parameter are meters. Frequency units are allowed.

Span 2 Stop Center–()=
The minimum value for Wavelength Span is 0.2 nm.
With Wavelength Limit Off, the maximum value for Wavelength Span is 1650 nm.
With Wavelength Limit On, the maximum value for Wavelength Span is 1100 nm.
The Preset value for Wavelength Limit is On. The Preset value for Wavelength Span is
1100 nm.
