DATA?

Queries the data resulting from delta, drift, and signal- to- noise mea- surements.

Syntax	:CALCulate3:DATA? {POWer FREQuency WAVelength WNUMber}
	Argument	Description
	POWer	Queries the array of laser-line powers after the calculation is
		completed.
	FREQuency	Queries the array of laser-line frequencies after the calculation is
		completed.
	WAVelength	Queries the array of laser-line wavelengths after the calculation is
		completed.
	WNUMber	Queries the array of laser-line wave numbers after the calculation
		is completed.
Attribute	Preset State: not affected
Summary	SCPI Compliance: standard
	Query Only
Description	The data returned by the query depends upon which calculation state
	is on. If no calculation state is on, an error is generated. The returned
	data is comma delimited. The following string is a typical example of
	six values returned when POWer is specified from a delta power mea-
	surement:

-7.42833100E+000,-1.00087200E+000,-2.52121400E+000, -3.41918900E+000,-3.80437200E+000,-6.36282900E+000

Notice that only measurement values are returned to the computer. There is no first value that indicates the number of values contained in the string as there is, for example, with the FETCh, READ, and MEASure commands. Use the CALC3:POIN? query to determine the number of points the CALC3:DATA? query returns.

In the SNR or ASNR calculation, only the POWer argument is valid. The other arguments will generate a “Settings conflict” error. Use the CALC2:DATA? query to retrieve the signal wavelengths and powers.
