MEASurement Commands
Measurement commands are high level commands used to acquire data.
They enable you to trade interchangeability against fine control of the
measurement process.
The CONFigure, FETCh?, READ? and MEASure? commands all have a
numeric suffix which refers to a specific window/measurement.

windows.

MEASure? Provides the simplest way to program a power meter for measurements.
MEASure? is a compound command which is equivalent to an ABORT
followed by a CONFigure and a READ?. It does not enable much
flexibility or control over measurement settings.
CONFigure Used to change the power meter’s configuration values. CONFigure
must then be followed by another command which takes the
measurement—for example, a READ? followed by a FETCh?.
READ? Takes a measurement using parameters previously set up using either
CONFigure or lower level commands. READ? is equivalent to an ABORt
followed by an INITiate1 (which performs the data acquisition) and a
FETCh?
FETCh?
Retrieves measurements taken by INITiate
