When this state is on, the power of the reference laser line is subtracted from
the power values of all laser lines except the reference.
The power data returned by the CALC3:DATA? query is the array of laser line
power levels normalized to the power level of the reference laser line. The
power of the reference laser line is returned as an absolute power (unnormal-
ized). The frequency data returned is the array of absolute frequency values.

Only one STATe command can be turned on at any one time. Attempting to turn more
