Description
DELTa:WAVelength[:STATe]
Turns the delta wavelength measurement mode on and off.
:CALCulate3:DELTa:WAVelength[:STATe]{?| {ON | OFF | 1 | 0}}
Preset State: off
*RST State: off
SCPI Compliance: instrument specific
When on, the wavelength of the reference laser line is subtracted from the wave-
length values of all laser lines except the reference.
For the CALC3:DATA? query, the power data returned is the array of absolute pow-
ers measured for each laser line. The frequency data is the array of frequency values
normalized to the frequency of the reference laser line. The frequency of the refer-
ence 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.
Refer to "Measure delta, drift and signal-to-noise" on page 94
information on selecting measurements.
