Long and short form
The mnemonics feature a long form and a short form. The short form is marked by
upper case letters, the long form corresponds to the complete word. Either the short
form or the long form can be entered; other abbreviations are not permitted.
Example:
HCOPy:DEVice:COLor ON
is equivalent to
HCOP:DEV:COL ON
.
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.
Example:
Definition:
HCOPy:PAGE:DIMensions:QUADrant[<N>]
Command:
HCOP:PAGE:DIM:QUAD2
This command refers to the quadrant 2.
Different numbering in remote control
For remote control, the suffix may differ from the number of the corresponding selec-
tion 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.
Example:
Definition:
HCOPy[:IMMediate]
Command:
HCOP:IMM
is equivalent to
HCOP
