SCPI Command Format

SCPI mnemonics have two forms: long and short. The short form is all in capital letters.

The long form is the entire mnemonic. Commands may use either the short form or the

entire long form. No other forms are accepted. SCPI ignores case: uppercase and

lowercase are equivalent.
A SCPI command is made by following the command tree as presented in the command

summary. Each level adds a mnemonic to the command separated by colons. Mnemonics

enclosed in square brackets are optional and may be omitted.
Some mnemonics are followed by an optional numeric suffix. If omitted, the suffix

defaults to 1.
Multiple commands may be placed in a single message separated by semicolons. Each

command starts at the same level of tree where the last command stopped unless the

command starts with a colon. The first command in a message and any commands

starting with a colon start of the root of the command tree. IEEE 488.2 commands may

occur between SCPI commands without affecting the tree level.
Command parameters are separated from the command name by one or more spaces.

Multiple parameters are separated by commas. SCPI accepts numeric parameters with

optional sign, decimal point, and exponent. OFF is equivalent to zero and ON is

equivalent to one. Floating point numbers are rounded to the nearest integer for

commands accepting integer values only.
A message is terminated by a Line Feed (hexadecimal 0A). Carriage Returns, Tabs, and

other control characters are ignored.

SCPI Response Format

Only commands ending in a question mark have responses. Multiple values from a single

command are separated by commas. Responses from different commands in the same

message are separated by semi-colons. The response message is terminated by a Line

Feed (hexadecimal 0A).
Integer responses are returned as one or more digits. Boolean values (ON and OFF values)

are always returned as numbers with zero for OFF and one for ON. Floating point values

are returned in the format “+d.ddddddddE+dd”.
