Page 71 Section 7 SCPI Outline The MP1777A adopts SCPI (Standard Commands for Programmable Instruments) as commands to perform remote con- trol. This section provides the outline of SCPI and explanations This section and subsequent Sectlons describe the examples of command use and response as follows.
Page 72: Outline
Section 7 SCPI Outline 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.
Page 73: Command Structure
Command Structure The SCPI command form a hierarchical structure. Commands are divided into groups, each of which consists of com- mands of similar functions, and each group forms 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.

Compounding Commands Commands can be compounded by using semi-colon 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 8 Device Message Details Buffer Size Stipulations A response in the format explained earlier is sent from the device to the controller. Therefore, the controller must have a buffer of a size enough to accept the response. When the commands of this device used, a maximum of 255 bytes of buffer space will suffice.
