Wavelength Commands
Set Wavelength
Syntax
[:SOURce]:WAVElength <val|MIN|MAX>
Description
Switches the laser to track mode and drives the laser
to the specified wavelength, the laser’s minimum
wavelength, or the laser’s maximum wavelength.
If the value is out of range, the laser returns an out
of range error and no other action is taken.
Argument
x.xxx
,
MIN
, or
MAX
Range: Within the laser’s minimum and maximum
wavelength range. (These values are laser depen-
dent; use the Query Wavelength command to deter-
mine your laser’s range.)
Units: nanometers (nm).
Example
Set the wavelength to 1525 nm.
:WAVE 1525
⇒
OK
(The wavelength starts changing at the maximum
rate until it reaches 1525 nm.)
Query Wavelength
Syntax
[:SOURce]:WAVElength[ MIN|MAX]?
Description
Queries the wavelength setpoint for track mode, or
the minimum or maximum available wavelengths.
Response
“x.xxxx”
Units: nanometers (nm).
Example
:WAVE?
⇒
1525.2552
(The wavelength is set to 1525.2552 nm)
:WAVE MIN?
⇒
1500.0000
(The minimum wavelength is 1500.0000 nm.)
