Multiple Commands in a Message Multiple SCPI commands can be combined and sent as a single message with one message terminator. There are two important considerations when sending several commands within a single Copyright © Itech Electronic Co., Ltd. - Page 14 Treat the common command as a message unit by separating it with a semicolon (the message unit separator).

Page 15: Message Type Of Scpi
Response message: A response message consists of data in a specific SCPI format sent from the instrument to the controller. The instrument sends the message only when commanded by a program message called a "query." The next figure illustrates SCPI message structure: Copyright © Itech Electronic Co., Ltd. - Page 16 (<NL>), decimal 10 or hexadecimal 0X0A in ASCII. ⚫ end or identify (<END>) ⚫ both of the above (<NL><END>). In the examples of this guide, there is an assumed message terminator at the Copyright © Itech Electronic Co., Ltd.

Page 17: Response Data Type
Each response is terminated with an LF (line feed) and EOI (end or identify). The following example shows how a multiple response message is terminated: 0; 1; 1; 0; <RMT> Message exchange protocol Two rules summarize the message exchange protocol: Copyright © Itech Electronic Co., Ltd. -
