CALibration Subsystem Commands
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 3-3
for additional information on this function.
CALibration:ALIGn:MARKer[1|2|3|4]
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 spec-
ified 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.
