Syntax for Device-Specific Commands
Long and short form
The mnemonics feature a long form and a short form. The short form is marked by
upper case letters here, to distinguish it from the long form, which constitutes the com-
plete word. Either the short form or the long form can be entered; other abbreviations
are not permitted.
Example:
INITiate:CONTinuous
is equivalent to
INIT:CONT
or
init:cont
.
Case-insensitivity
Upper case and lower case notation only serves to distinguish the two forms in the
manual, the instrument itself is case-insensitive.
Numeric suffixes
If a command can be applied to multiple instances of an object, e.g. specific channels
or sources, the required instances can be specified by a suffix added to the command.
Numeric suffixes are indicated by angular brackets (<1...4>, <n>, <i>) and are replaced
by a single value in the command. Entries without a suffix are interpreted as having the
suffix 1.
Different numbering in remote control
For remote control, the suffix can differ from the number of the corresponding selection
used in manual operation. SCPI prescribes that suffix counting starts with 1. Suffix 1 is
the default state and used when no specific suffix is specified.
Some standards define a fixed numbering, starting with 0. If the numbering differs in
manual operation and remote control, it is indicated for the corresponding command.
Optional mnemonics
Some command systems permit certain mnemonics to be inserted into the header or
omitted. These mnemonics are marked by square brackets in the description. The
instrument must recognize the long command to comply with the SCPI standard. Some
commands are considerably shortened by these optional mnemonics.
