Controlling the OBR Remotely
7
Description: Queries whether the wavelength calibration failed during
the previous scan. It is analogous to the “Wavelength Cal
Failed” warning light that appears in the OBR software.
Response: Returns 1 if the wavelength calibration failed, or 0 if it did
not. Note that this only applies to scans started remotely
(using the SCAN or SYST:SPOT commands), not scans that
were performed using the local Scan button.
Example:
SYST:WCLF?
This query returns the value 1 or 0, depending on whether
the wavelength calibration failed or not.
SYSTem:ReLoaDCalibration
Usage:
SYST:RLDC
Description: Reloads into memory the calibration file set by
SYST:CALF (described below).
Response: None.
Note: The user may send this command if SYST:CAL? returns a
“0,” indicating that the calibration failed. Alternately, the
user may recalibrate using the or SYST:CAL command
described above.
SYSTem:CALibrationFile
Usage: SYST:CALF {0, filename}
Description: Sets the name of the calibration file. If the filename is not
specified, this command sets calibration file to the default
filename, obrCal_refl.
Because this command is used for other Luna systems, the
user must specify zero (0) with this command for a
reflection calibration.
Response:
None.
Example: SYST:CALF 0,
c_band
This instructs the OBR to use the "c_band" calibration file.
SYST:CALF 0
This instructs the OBR to use the default calibration file,
obrCal_refl.
