7-6 Remote Operation and Commands Model 6485 and 6487 User’s Manual
SCPI command subsystems
Table 7-4 summarizes the various SCPI subsystems used to program most Model 6485/
6487 operations. Detailed lists of commands ass
ociated with these subsystems are located
in Section 14 of the Model 6485 Instruction Manual or Model 6487 Reference Manual.

Programming syntax
The following paragraphs cover syntax for both common commands and SCPI com-
mands. For more information, see the
IEEE-488.2 and SCPI standards.
Command words
Program messages are made up of one or more command words. Common commands and
SCPI commands may or may not use a parameter. There must be at least one space
between the command word and its parameter. 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.
Common commands and SCPI commands
are not case sensitive. You can use upper or
lower case and any case combination. A SCPI command word can be sent in its long-form
or short-form version. The command tables in this manual use the short-form version. You
can send multiple command messages in the same program message as long as they are
separated by semicolons (;).
