CONFigure:STARt
Usage: CONF:STAR {startWavelength}
Description: Sets the start wavelength for the scan in nanometers. The
wavelength parameter must be within the operating range
of the instrument.
If the start wavelength falls outside the limits of the
instrument, the command is accepted, but the start
wavelength will be coerced to the nearest wavelength within
the OBR’s limits using the current setting of Wavelength
Range.
Response: None.
Notes: Setting the start wavelength will cause the center and end
wavelengths to be adjusted to match the new start
wavelength and the wavelength range set using the
CONF:RANG command.
Example: CONF:STAR 1525.0
This command sets the starting wavelength to 1525.0 nm.
CONFigure:STARt?
Usage: CONF:STAR?
Description: Retrieves the current start wavelength in nanometers.
Response:
Returns the current start wavelength in nanometers.
Example:
CONF:STAR?
This query returns a message in the form “1525.00.”
CONFigure:END?
Usage: CONF:END?
Description: Queries the OBR for the current ending wavelength.
Response: Returns the current ending wavelength in nanometers.
Example: CONF:END?
This query returns a message in the form “1590.00” nm.
CONFigure:RANGe
Usage: CONF:RANG {scanRange}
Description: Sets the Scan Range in nanometers. The OBR only allows
scan ranges that have a number of data points equal to a
