Agilent Technologies Agilent 86120C manual DRIFtSTATe, Syntax, Attribute, Summary, Description

Programming Commands

CALCulate3 Subsystem

	DRIFt[:STATe]
	Turns on and off the drift measurement calculation.
Syntax	:CALCulate3:DRIFt[:STATe]{? {ON OFF 1 0}}
Attribute	Preset State: off
Summary	*RST State: off
	SCPI Compliance: instrument specific
Description	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 wave-
	lengths and powers.
	The CALC3:DATA? query returns the power and frequency of the cur-
	rent measurement 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 3-14 for additional informa-
	tion on selecting measurements.
