Command and Query Notational Conventions
To distinguish the command types in the command descriptions, a question mark is included alone or within parentheses, or it is omitted.
• If the command syntax ends with (?), then it can be both a command and a query.
• If the command syntax ends with ?, then it is a query only.
• If the command syntax ends without a ?, then it has no query form.
Examples:
Select Mode by Number
:INSTrument:NSELect <integer>(?)
(both a command and a query – full description)
Query Available Modes
:INSTrument:CATalog:FULL?
(a query only – full description)
Delete Data/Location
:MMEMory:DELete <filename>
(no query – full description)
