17.14.4 Data export of spectrum waveforms
For each of the spectrum traces, a dedicated command is available. For a description
of the traces, see "Traces" on page 249.
CALCulate:SPECtrum<sp>:WAVeform:AVERage:DATA:HEADer?
CALCulate:SPECtrum<sp>:WAVeform:MAXimum:DATA:HEADer?
CALCulate:SPECtrum<sp>:WAVeform:MINimum:DATA:HEADer?
CALCulate:SPECtrum<sp>:WAVeform:NORMal:DATA:HEADer?
Returns the header of spectrum data. The header contains attributes of the waveform.

CALCulate:SPECtrum<sp>:WAVeform:AVERage:DATA[:VALues]?
[<Offset>[,<Length>]]
CALCulate:SPECtrum<sp>:WAVeform:MAXimum:DATA[:VALues]?
[<Offset>[,<Length>]]
CALCulate:SPECtrum<sp>:WAVeform:MINimum:DATA[:VALues]?
[<Offset>[,<Length>]]
CALCulate:SPECtrum<sp>:WAVeform:NORMal:DATA[:VALues]?
[<Offset>[,<Length>]]
Returns the data of the spectrum points for transmission from the instrument to the
controlling computer. The data can be used in MATLAB, for example.
Without parameters, the complete waveform is retrieved. Using the offset and length
parameters, data can be retrieved in smaller portions, which makes the command
faster. If you send only one parameter, it is interpreted as offset, and the data is
retrieved from offset to the end of the waveform.
To set the export format, use FORMat[:DATA] on page 483.
