:MEASure Subsystem

The :MEASure subsystem commands allow you to configure the instrument,
initiate measurements, and place the results in the Output Queue using a
minimum number of commands. These commands are described in detail in this
section.

Measurement Instructions (:CONFigure, :FETCh, :MEASure, :READ)

The purpose of these commands is to acquire data using a set of high-level
instructions. These commands are structured to allow you to trade off
interchangeability between instruments. The :MEASure query provides the ability
to configure the instrument, take a measurement, and store the results in the
Output Queue in a single operation.
When more precise control of the measurement is required, the :CONFigure and
:READ? commands can be used. The :CONFigure command is used to configure
the instrument for the measurement to be taken, and the :READ? command
acquires the data, performs any required post processing, and then places the
results in the Output Queue. This allows you to configure the instrument
generically (using :CONFigure) and then to customize the measurement with
other commands (for example, commands from the [:SENSe] subsystem). The
:READ? command completes the measurement process.
The :READ? command is composed of the :INITiate[:IMMediate] and :FETCh?
commands. :INITiate[:IMMediate] performs the data acquisition. :FETCh?
performs the post-processing function (if any) and places the result in the Output
Queue. This allows more than one FETCh? on a single set of acquired data.
The functions of the measurement instruction commands are summarized in
