Parameters: Units of Measure and Multipliers
Refer to IEEE 488.2, section 7.7.3 for the definition of units of measure. The default units of
measure include:
•
V (Volt - voltage)
•
A (Ampere - current)
•
W (Watt - power)
•
S (seconds - time)
These units are only supported as defaults. To place the unit in the command will cause
an error to be pushed into the error queue.
SCPI Command Hierarchy
SCPI is an ASCII-based command language designed for use in test and measurement
equipment. The command structure is organized around common roots, or nodes, which are
the building blocks of SCPI subsystems. An example of a common root is CALibration, and
some of the commands that reside in the CALibration subsystem are:
[:]CALibration
[:OUTPut]
[:VOLTage]
[:DATA]<NR1>
:CURRent
[:DATA]<NR1>
CALibration is the root keyword of the command. OUTPut is a second-level keyword, and
VOLTage and DATA are third-level keywords. A colon (:) is used to separate a command
keyword from a lower-level keyword.
