In this appendix:
Introduction
This section describes the general bus commands and common commands. Note that although these
commands are essentially the same as those defined by the IEEE Std 488.2 standard, the Model
2450 does not strictly conform to that standard.
The general bus commands are commands that have the same general meaning, regardless of the
instrument (for example, DCL always clears the GPIB interface and returns it to a known state).
The common commands perform operations such as reset, wait-to-continue, and status.
Common commands always begin with an asterisk ( * ) and may include one or more parameters.
The command keyword is separated from the first parameter by a blank space.
If you are using the TSP remote interface, each command must be sent in a separate message.
If you are using a SCPI remote interface, the commands can be combined. Use a semicolon ( ; ) to
separate multiple commands, as shown below:
*RST; *CLS; *ESE 32; *OPC?
Although the commands in this section are shown in uppercase, common commands are not case
sensitive (you can use either uppercase or lowercase).
If you are using the TSP remote interface, note that the common commands cannot be used in
scripts.
