5.3.5.3 Common Command and Query Headers
The syntax of common command and query headers is described in IEEE 488.2. It is used
together with the IEEE 488.2-defined common commands and queries. The commands with
a leading “ * ” are common commands.
5.3.5.4 Instrument-Controlled Headers
Instrument-controlled headers are used for all other instrument commands. Each of them has
a long form and a short form. 62000H Series only accepts the exact short and long forms. A
special notation will be taken to differentiate the short form header from the long one of the
same header in this subsection. The short form header is shown in characters of upper case,
whereas the rest of the headers are shown in those of lower case.
5.3.5.5 Program Header Separator (:)
If a command has more than one header, the user must separate them with a colon
(FETC:CURR FUNC:SHAP). Data must be separated from program header with one space
at least.
5.3.5.6 Program Message
Program message consists of a sequence of zero or other elements of program message
unit that are separated by separator elements of program message unit.
5.3.5.7 Program Message Unit
Program message unit represents a single command, programming data, or query.
Example: VOLT?, OUTPut ON.
5.3.5.7.1 Program Message Unit Separator (;)
The separator (semicolon ;) separates the program message unit from one another element
in a program message.
Example:
VOLT
80; CURR
15<P
MT>
5.3.5.7.2
Program Message Terminator (<PMT>)
A program message terminator represents the end of a program message. Three permitted
terminators are:
(1) <END> : end or identify (EOI)
(2) <NL> : new line which is a single ASCII-encoded byte 0A (10 decimals).
(3) <NL> <END> : new line with EOI.
