6. Command Set Organization
Beginning with Section 7, descriptions are given of the commands, queries, and responses as implemented in the
analyzer. The sections are organized by command groupings. Typically, commands from the same group will
begin with the same alphabetic character.
Each of the following sections provides a brief table of the commands within the group. The table also describes
the allowed Window Levels and
Window Levels
The analyzer CRT display supports multiple window levels. Different types of information are displayed in
particular windows. For example, the Base window is used the majority of the time. This window presents the
display in a Help window. The following table describes the window levels that are used by the analyzer.
Base
Level 1
Level 2
Level 3
Level 4
Level 5
Level 6
Commands and queries are allowed in different window levels, based upon the actions the analyzer must perform
to carry out the command or query. Each command group table in the following sections specifies at which
window levels each command is allowed. The analyzer will generate an Invalid Mode Error (Error 09) if an
attempt is made to execute a command or query at an incorrect window level.
Command Transparency
There are a class of commands that are transparent to ongoing operations that the analyzer is executing. These
commands and queries typically provide status or special control capabilities that deal with the manner in which
the remote interface operates. For example, the common command *E-SE may be issued at any time without
affecting any operation associated with the above commands and queries.
Sequential and Overlapped Commands
Commands and queries may be executed as either sequential or overlapped, as defined by IEEE 488.2.
Overlapped commands may execute in parallel with other commands. All commands and queries implemented by
the analyzer are sequential.
