SCPI Measurement Commands
Configure Commands:
:CONFigure:<measurement>
This command stops the current measurement (if any) and sets up the instrument for the
specified measurement using the factory default instrument settings. It does not initiate the
taking of measurement data unless INIT:CONTinuous is ON. If you change any measurement
settings after using the CONFigure command, the READ command can be used to initiate a
measurement without changing the settings back to their defaults.
:CONFigure:NDEFault<measurement> stops the current measurement and changes to the
specified measurement. It does not change the settings to the defaults. It does not initiate the
taking of measurement data unless INIT:CONTinuous is ON.
The CONFigure? query returns the current measurement name.
Fetch Commands:
:FETCh:<measurement>[n]?
This command puts selected data from the most recent measurement into the output buffer. Use
FETCh if you have already made a good measurement and you want to return several types of
data (different [n] values, for example, both scalars and trace data) from a single measurement.
FETCh saves you the time of re-making the measurement. You can only FETCh results from the
measurement that is currently active, it will not change to a different measurement. An error is
reported if a measurement other than the current one, is specified.
If you need to get new measurement data, use the READ command, which is equivalent to an
INITiate followed by a FETCh.
The scalar measurement results will be returned if the optional [n] value is not included, or is set
to 1. See each command for details of what types of scalar results or trace data results are
available. The binary data formats should be used for handling large blocks of data since they are
smaller and transfer faster then the ASCII format. (FORMat:DATA)
FETCh may be used to return results other than those specified with the original READ or
MEASure command that you sent.
