Tektronix OA 5000 Commands

OA 5000 Series User Manual 3 --- 1 3

Commands

OA 5000 commands fall into two main groups: Common Commands and

Device Commands. The commands followTektronix Standard Codes and

Formats1991.

Most of these commands can be used eitheras set commands or queries.

However,some commands can only be used to set: these have the words

“No QueryForm”included with the command name. Other commands can

only be used toquery: these have a question mark appended to the header,

and include the words “Query Only”in the command name.

Headers, mnemonics, and arguments are usuallyspelled out fully in text,

with the minimum required spelling show n in upper case. For example, to

use the command RECall youmust enter at least REC. The examples in this

manual use the abbreviated forms.

Several commands and queries used with the OA5000 are common to all

devices on the GPIB. These commands and queriesare defined by IEEE

Std 488.2-1987 and TektronixStandard Codes and Formats 1991 as useful

across all instrumentsin a GPIB system.

Table3-4 lists the Common Commands supported by the OA 5000. Com-

plete descriptionsof these commands appear in an alphabetical listing of

commands later in thissection.
