Preset State: 1270 nm (236.0571 THz)
*RST State: 1270 nm (236.0571 THz) laser line
SCPI Compliance: instrument specific
The reference will be the laser line at the wavelength
closest to the wavelength entered. Subsequent mea-
surements will use the wavelength closest to the refer-
ence wavelength used for the previous measurement.
The query returns the current wavelength of the refer-
ence laser line. The default units for the <real> param-
eter are meters.
Turns the delta wavelength measurement mode on and
off.
Preset State: off
*RST State: off
SCPI Compliance: instrument specific
When on, the wavelength of the reference laser line is
subtracted from the wavelength values of all laser lines
except the reference.
For the CALC3:DATA? query, the power data returned
is the array of absolute powers measured for each laser
line. The frequency data is the array of frequency val-
ues normalized to the frequency of the reference laser
line. The frequency of the reference laser line is
returned as an absolute frequency (unnormalized).
Note
Only one STATe command can be turned on at any one time.
Attempting to turn more than one state on at a time results in a
"–221 Settings Conflict" error.
