Page 13: Chapter1 Scpi Introduction
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 message: ⚫ Use a semicolon to separate commands within a message. Copyright © ITECH Electronic Co., Ltd. - Page 14 VOLTage:TRIGgered 17.5;:INITialize;*TRG OUTPut OFF;*RCL 2;OUTPut ON Case Sensitivity Common commands and SCPI commands are not case sensitive. You can use upper or lower for example: *RST = *rst Copyright © ITECH Electronic Co., Ltd.

Page 15: 1.3 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 An invalid command generates an error and, of course, is not executed. ⚫ Valid commands that precede an invalid command in a multiple command program message are executed. ⚫ Valid commands that follow an invalid command in a multiple command program message are ignored. Copyright © ITECH Electronic Co., Ltd.

Page 17: 1.4 Response Data Type
Rule 2: The complete response message must be received by the computer before another program message can be sent to the instrument. 1.5 Command Format Formats for command display are as follows: [SOURce[1|2]:]VOLTage:UNIT {VPP|VRMS|DBM} Copyright © ITECH Electronic Co., Ltd. - Page 18 It is used to separate several commands in the same subsystem and can also minimize typing. For example, to send the following command string: TRIG:SOUR EXT; COUNT 10 has the same effect as sending the following two commands: TRIG:SOUR EXT TRIG:COUNT 10 Copyright © ITECH Electronic Co., Ltd.
