Command Guidelines

Measurement Subsystems

Measure Subsystem

Commands

Measure commands are used to control measurements and get back

the value of the displayed measurement. To get a valid measurement,

the instrument must ﬁrst be set up to access the desired measurement.

In most cases, this means that you must be on the screen (or set of

screens) associated with the measurement. For example, to retrieve

Output RF Spectrum measurement results, you must be on the Output

RF Spectrum ’Main’ screen or ’Trace’ screen. (See the DISPlay

subsystem commands.) The Trigger commands are then used to cause

a measurement to occur. Once a measurement result is available it

may be queried.

Syntax Diagrams

Each GPIB Subsystem chapter starts with a syntax diagram. This diagram uses a graphical

format to represent the hierarchical structure of a subsystem. The diagram also indicates

possible options and references to other command sets.

The following describes two graphical conventions used in the syntax diagrams.

Means a space must be used as part of the command line. For

example;

AFAN:AIN<space>‘GND’

Represents a colon in the command line.

AFAN:AIN ‘GND’
