Section 7 SCPI Outline The MP1777A adopts SCPI (Standard Commands for Programmable Instruments) as commands to perform remote control. This section provides the outline of SCPI and explanations of the command system. This section and subsequent Sectlons describe the examples of command use and response as follows. > Program message (program command. query command) < Response 7.1 Outline .............................................................................................. 7.2 Command Structure ...
Section 7 SCPI Outline 7.1 Outline SCPI is a device command language defined by the SCPI consortium and is independent from the hardware. SCPI is designed to shorten the period for development of automatic measuring instrument (ATE). For this reason, the programming environments such as the device control and data handling are made consistent.
7.2 Command Structure 7.2 Command Structure The SCPI command form a hierarchical structure. Commands are divided into groups, each of which consists of commands of similar functions, and each group forms a hierarchical structure called the subsystem. This specification expresses these subsystems by the command tree as shown below. SCPI allows the same headers to be present in a tree and the difference in the location of the header corresponds to the difference in the function.
Section 7 SCPl Outline Command Description Method : SOURce : SOURce : SOURce : SOURce : TELecom : TELecom : TELecom : TELecom : BRATe ~ b r a t e > : BRATe? : EQUAlizer : EQUAlizer? Fig. 7-2 Example of SCPl Commands The command tree shown in the previous section consists of the commands shown above. The section below provides explanations of the stipulations concerning descriptions of commands. A command begins with a colon ( : ).
7.4 Compounding Commands 7.4 Compounding Commands Commands can be compounded by using semi-colon ( ; ) as shown by the example below. The second command is also referenced as the command located at the same level as the lowest hierarchical level of the first command. For this reason, the second command can be described in a full path as shown by Example 1. However, as Example 2 shows, headers located in the layer above Type can also be abbreviated.
Section 7 SCPI Outline Parameter The table below shows types of parameters used by this measuring instrument This operation manual expresses parameter types in lowercase characters enclosed by angled brackets ( < and > ) in the table below. Moreover, the type corresponding to the parameter type, specified by IEEE488.2 (or SCPI), is expressed in uppercase characters. The correspondence between each parameter type and specified by IEEE488.
