CALibration Subsystem Commands

CALibration:ALIGn

Performs an automatic alignment of the instrument at the wavelength of the largest signal found in full span. This aligns the monochrometer output with the photodetector for improved amplitude accuracy. Sending this command with a marker on screen will generate a “Settings conflict” error. See page 3-3for additional information on this function.

CALibration:ALIGn:MARKer[1234]

Performs an automatic alignment of the instrument at the wavelength of the specified marker. This aligns the monochrometer output with the photodetec- tor for improved amplitude accuracy. Sending this command without the specified marker on will generate a “Settings conflict” error.

CALibration:ALIGn:EXTernal

Performs an alignment of the instrument using an external broadband source. The instrument performs an alignment at each of several wavelengths and stores the values in a wavelength alignment table. This results in improved amplitude accuracy.

CALibration:ALIGn:PRESET

Sets the alignment of the instrument to the preset factory-calibrated values.

CALibration:DATE?

Returns the date of the most recent factory calibration.
