Chapter 6 SCPI Command Reference
6.1 Command structure
TH1952 command system adopts SCPI commands. The SCPI commands are tree structured three
levels deep. (The highest level commands are called the subsystem commands in this manual.) So the
lower level commands are legal only when the subsystem commands have been selected. A colon (:) is
used to separate the higher level commands and the lower level commands. See Figure 6-1 for a
sample.

6.2 Command Syntax
The information in this section covers the syntax for both common commands and SCPI commands.
6.2.1 Commands and command parameters
Common commands and SCPI commands may or may not use a parameter. The following are some
examples:
*RST No parameter used
:FORMat <name> Parameter<name> required
:IMMediate No parameter used
Put at least one space between the command word and the parameter.
Brackets [ ]: Some command words are enclosed in brackets. These brackets are used to denote
an optional command word that does not need to be included in the program message. For
example:
:RANGe[:UPPer] <n>
