Page 14: Chapter1 Scpi Introduction
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 message: Copyright © Itech Electronic Co., Ltd.
Page 15 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: Copyright © Itech Electronic Co., Ltd.
Page 16: 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 17 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 18: 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 19 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.
Page 20: 1.6 Data Type
In all cases, the program must read <NL> in response before another command is sent to the instrument, otherwise errors will be caused. 1.6 Data Type SCPI language defines several data types used for program message and response messages. Copyright © Itech Electronic Co., Ltd.
Page 21: 1.7 Remote Interface Connections
– <SPD>: string program data. String parameters enclosed in single or double quotes. – <CPD>: character program data. 1.7 Remote Interface Connections Please refer to user manual for detailed introductions of the remote interface. Copyright © Itech Electronic Co., Ltd.
Page 22 If the user want to change the settings of the instrument, for instance, the output setting value, the command SYST:REM must be sent to the instrument after finishing the connection between the instrument and PC. Copyright © Itech Electronic Co., Ltd.
