SCPI Compliance: instrument specific
When the drift mode is first turned on, the current list of laser lines is placed into the
reference. All subsequent measurements take the new data, subtract the reference
data, and display the differences in wavelengths and powers.
The CALC3:DATA? query returns the power and frequency of the current measure-
ment minus the power and frequency of the reference.
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.
