Programming Commands

CALCulate3 Subsystem

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.
