Introduction to SCPI command SCPI (Standard Commands for ProgrammMable Instruments abbreviation), that is, the standard command set of program control instruments (programmable instruments). SCPI is a standardized instrument based on the existing standard IEEE 488.1 and IEEE 488.2, and follows the standardized instruments of the floating-point computing rules of the IEEE 754 standard, ISO 646 information exchange 7-bit encoding symbols (equivalent to ASCII programming). programming language. The SCPI command is a tree-like structure, including multiple subsystems. Each subsystem consists of a root keyword and one or several layers of keywords.

Command format The command usually starts with the colon ":". The keywords are separated by the colon ":", followed by the optional parameter settings behind the keywords. Add a question mark "?" Behind the command line, indicating that this function is queried. The command keyword and the first parameter are separated by space, for example: :ACQuire:TYPE :ACQuire:TYPE? Acquire is the root keyword of the command, and Type is the second-level keyword. The command line starts with the colon ":", and at the same time use the colon "::" to separate the keywords at all levels. indicates the settable parameter. The question mark "?" Indicates the query. Command keywords: Acquire:

Type and parameters are separated by spaces. In some commands with parameters, the comma ",", "separate multiple parameters, for example: [:TRACe[ ]]:DATA:VALue volatile, , Symbol Description The following symbols are not sent with commands. 1. Braces {} The content in the brackets is the parameter option. Parameters are usually separated by vertical lines "|". When using the command, one of the parameters must be selected. 2. Vertical line | The vertical line is used to separate multiple parameter options, and one of the parameters must be selected when using the command. 3. Square bracket [] The content in square brackets is omitted.

4. Triangle bracket The parameters in the triangular bracket must be replaced with an effective value. Parameter Type 1. Bool The parameter is ON, OFF, 1 or 0. For example: :MEASure:ADISplay :MEASure:ADISplay? Among them: can be set to:{{1|ON}|{0|OFF}}. Query back 1 or 0 2. Discrete The parameter takes the option listed. For example: :ACQuire:TYPE :ACQuire:TYPE? Among them: can be set as: NORMal|AVERages|PEAK|HRESolution. Query Return to abbreviations: NORM, AVER, PEAK or HRES. 3. Integer Unless there is another instructions, the parameters can be an arbitrary integer (NR1 format) within the effective value range.

Note that at this time, please do not set the parameter as a decimal format, otherwise there will be abnormalities. For example: :DISPlay:GBRightness :DISPlay:GBRightness? Among them: can be set to: Our integer between 0 and 100. The query returns an integer between 0 and 100. 4. Real The parameters can be arbitrarily numbered within the valid value range. The command accepts the parameter input of the decimal (NR2 format) and the scientific count (NR3 format) format. For example: :TRIGger:TIMeout:TIMe :TRIGger:TIMeout:TIMe? Among them: The parameter can be set to a real number between 1.6e-08 (ie 16ns) and 1e+01 (ie 10s). The query returns a real number in the scientific 5.

ASCII String counting format. The combination of the parameter is the combination of ASCII characters, for example: :SYSTem:OPTion:INSTall Among them: can be set to: PDUY9N9QTS9PQSWPLAETRD3UJHYA Order abbreviation
