C.1 An Introduction to the SCPI Language
SCPI (
Standard Commands for Programmable Instruments
) is an
ASCII-based instrument command language designed for test and
measurement
instruments.
Refer
to
“Simplified
Programming
Overview,” for an introduction to the basic techniques used to program
the multimeter over the remote interface.
SCPI commands are based on a hierarchical structure, also known as a
tree system
. In this system, associated commands are grouped together
under a common node or root, thus forming
subsystems
. A portion of the
SENSe subsystem is shown below to illustrate the tree system.
[SENSe:]
VOLTage:
DC:RANGe {<
range
>|MINimum|MAXimum}
VOLTage:
DC:RANGe? [MINimum|MAXimum]
FREQuency:
VOLTage:RANGe {<
range
>|MINimum|MAXimum}
FREQuency:
VOLTage:RANGe? [MINimum|MAXimum]
DETector:
BANDwidth {3|20|200|MINimum|MAXimum}
DETector:
BANDwidth? [MINimum|MAXimum]
ZERO:
AUTO {OFF|ONCE|ON}
ZERO:
AUTO?
SENSe is the root keyword of the command, VOLTage and FREQuency
are second-level keywords, and DC and VOLTage are third-level
