1.1. About Commands & Queries This section lists and describes the remote control commands and queries recognized by the instrument. All commands and queries can be executed in either local or remote state. The description for each command or query, with syntax and other information, begins on a new page. The name (header) is given in both long and short form, and the subject is indicated as a command or query or both.
placeholders, of which there are two types: the header path and the data parameter of a command. := A colon followed by an equals sign separates a placeholder from the description of the type and range of values that may be used in a command instead of the placeholder. { } Braces enclose a list of choices, one of which one must be made. [ ] Square brackets enclose optional items. … An ellipsis indicates that the items both to its left and right may be repeated a number of times.
1.2. Table of Commands & Queries Short Long Form Subsystem What Command/Query dose *OPC *OPC SYSTEM Get or set the OPC bit (0) in the Event Status Register (ESR).
1.3. IEEE 488.2 Common Command Introduction IEEE standard defines the common commands used for querying the basic information of the instrument or executing basic operations.
