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)
The supported optional multipliers include:
• m (milli)
• k (kilo)
SCPI Command Hierarchy
SCPI is an ASCII-based command language designed for use in high-technology 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 shown below.
CALibration
:CURRent
[:DATA] <numeric value>
:LEVel {MIN|MAX}
[:SECure]
:CODE <new code>
:STATe {OFF|ON}, <code>
:STATe?
CALibration is the root keyword of the command. CURRent and SECure are
second-level keywords, and DATA, LEVel, CODE, and STATe, are third-level
keywords. A colon (:) is used to separate a command keyword from a lower-level
keyword.
Note The SI standard for these multipliers is specifically lowercase, while the IEEE
standard specifies uppercase. Both combinations are supported.
