Overview of Command Types and Formats
There are two types of Keysight 53147A/148A/149A programming commands:
IEEE 488.2 Common Commands and Standard Commands for Programmable
Instruments (SCPI). The format of each type of command is described in the
following paragraphs. (Refer to the section titled
page 139 for SCPI conformance information.)
Common Command Format
The IEEE 488.2 Standard defines Common Commands as commands that perform
functions like reset, self-test, status byte query, and identification. Common
Commands always begin with the asterisk (*) character, and may include
parameters. The command keyword is separated from the first parameter by a
space character. Some examples of Common Commands are as follows:
*RST
*IDN?
*RCL 1
SCPI Command and Query Format
SCPI commands perform functions like instrument setup. A subsystem command
has a hierarchical structure that usually consists of a top level (or root) keyword,
one or more lower-level keywords, and parameters. The following example shows
a command and its associated query:
:DISPlay:ENABle:ON
:DISPlay:ENABle?
In this example,
DISPlay
is the root-level keyword,
ENABle
is the second-level
keyword, and
ON
is the command parameter.
