Set Wavelength Offset
Syntax
[:SOURce]:WAVElength:OFFSet <val>
Description
Allows you to recalibrate the laser to an external
wavelength meter.
Argument
x.xxx
Range: ±2.5.
Units: nanometers (nm).
Example
Using an external wavelength meter, you notice that
the wavelength display on the laser’s front panel is
0.2-nm more than the reading on the meter.
:WAVE:OFFS -0.2
⇒
OK
(You will not notice a difference without using an
external wavelength meter.)
Query Wavelength Offset
Syntax
[:SOURce]:WAVElength:OFFSet?
Description
Checks the value of the wavelength offset.
The units are in nanometers.
Response
“x.xxxxx”
Units: nanometers (nm).
Example
:WAVE:OFFS?
⇒ −
0.03000
(The wavelength has been offset by -0.030 nm from
the factory-calibrated setting.)
