SCPI programming
SCPI programming information is integrated with front panel operation throughout this
manual. SCPI commands are listed in tables and additional information that pertains
exclusively to remote operation is provided after each table. The SCPI tables may refer-
ence you to other sections of this manual.
NOTE SCPI tables in this manual are abridged. That is, they do NOT include most
optional command words and query commands. See Section 14 of the
Model 6485 Instruction Manual or Model 6487 Reference Manual for a com-
plete listing of SCPI commands.
Optional command words
In order to be in conformance with the IEEE-488.2 standard, the Model 6485/6487
accepts optional command words. Any command word that is enclosed in brackets ([]) is
optional and does not have to be included in the program message. Programming exam-
ples in this manual use the short form and do not include optional command words for
simplicity.
Query commands
Most command words have a query form. A query command is identified by the question
mark (?) that follows the command word. A query command requests (queries) the pro-
grammed status of that command. When a query command is sent and Model 6485/6487
is addressed to talk, the response message is sent to the computer.
