Chapter 6 SCPI communication protocol.
6.1 SCPI command overview
MPS-3600H series programmable DC power supply supports SCPI communication
protocol.Scpi is a standard command for programmable instruments. It defines a set of
command rules for communication. Commands for iv3600 series power are divided
into two main categories: basic command (ieee-488.2 common command set) and
MPS-3600H series specified command set.
The SCPI commands are arranged in a hierarchy of command trees. Each command
contains many strings (mnemonic symbols), and the layers are separated by colon (:).
The command at the top of the command tree is called "root command" or "root". To
access the next command, a path must be specified. The structure of the command
tree is as follows:
In the graph, AA represents the root path; BB, CC, DD represent the direct subpath.Ee
under the root path, FF, GG represents the subpath. Hh under the subpath BB, and JJ is the
subpath under the subpath DD.
Command description:
1) [:]aa:cc indicates that the root path is AA, and cc. is accessed under AA.
2) [[]aa:bb:ff] indicates that the root path is AA, and the ff. under the subpath BB under
the AA root path is accessed.
3) [[]aa:dd:hh] indicates that the root path is AA, and the hh. under the subpath DD
