Programming Commands
CALCulate3 Subsystem
DATA?
Queries the data resulting from delta, drift, and signal-to-noise measurements.
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 Summary Preset State: not affected
SCPI Compliance: standard
Query Only
Description The data returned by the query depends upon which calculation state is on. If no cal-
culation 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 measurement:
-7.42000,-1.00000,-2.52000,
-3.41000,-3.80000,-6.36000
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 argu-
ments will generate a “Settings conflict” error. Use the CALC2:DATA? query to
retrieve the signal wavelengths and powers.
