5.6 Command Explanation
5.6.1 Summary of Terms
Summary of terms used are explained below.
5.6.1.1 Subsystem Commands
Commands are divided into groups depending on their function. Subsystem commands are
arranged in a hierarchy. The colon ( : ) is defined as the path separator.
5.6.1.2 Path Separator
The path separator ( : ) separates the current keyword from the keywords one level lower.
In a command character string, each colon ( : ) indicates a displacement to the path one level
below the current path.
When the colon ( : ) is found at the beginning of a command character string it means “to set
the current path to root”. The current path is also set to root by the power on, *RST
command, or message terminator. The beginning of a program message is always set to root.
A colon ( : ) at the beginning of a command character string is omissible arbitrarily.
: S Y S T: K L O C 1
(1) Set current path to root (Omissible)
(2) SYSTem subsystem command (SYSTem is a root command)
(3) SYSTem subsystem attached KLOCk command
(4) A space is reqired between the header and the parameters
By separating the commands with a semicolon ( ; ), plural command character strings can be
put together into one program message.
:CALC1:MATH:STAT ON ; :CALC1:MATH:EXPR:NAME PCNT
Command 1 Command 2
The above example shows one program message equivalent to the following two
program messages.
:CALC1:MATH:STAT ON Current path after execution is :CALC1:MATH:
:CALC1:MATH:EXPR:NAME PCNT Current path after execution is:CALC1:MATH:EXPR:
If a colon ( : ) is omitted in the second and subsequent command character strings, the
subsystem command on the same level is accessible without changing the current path.
:CALC1:MATH:STAT ON ; EXPR:NAME PCNT In second command:CALC1:MATH:
is omissible
In both cases, the program message terminator at the end is omitted.
