When this command is set to on, the CALC3:DATA? command returns the ref-
erence laser lines. Use the CALC3:DRIF:PRES command to turn off all the
drift states before turning on the drift reference state.
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 4-14 for additional information on selecting
measurements.
