Introduction to the SCPI Language

Introduction to the SCPI Language
Syntax
SCPI commands present a hierarchical tree structure and contain multiple sub-systems, each of
which is made up of a root keyword and one or more sub-keywords. The command string usually
starts with ":", the keywords are separated by ":" and are followed by the parameter settings
available, "?" is added at the end of the command string to indicate query and the command and
parameter are separated by "space".
For example:
SENSe:VOLTage:DC:RANGe {<range>|MINimum|MAXimum}
SENSe:VOLTage:DC:RANGe? [{MINimum|MAXimum}]
SENSe is the root keyword of the command. VOLTage and DC are the second-level and
third-level keywords respectively. The command string starts with ":" which separates the
multiple-level keywords. <range> represents parameters available for setting, "?" represents
query and the command : SENSe:VOLTage:DC:RANGe and the parameter
{<range>|MINimum|MAXimum} are separated by "space".
Syntax Rules
SCPI language itself defines a group of sub-system keywords, and at the same time allows users
to add or reduce keywords. Those keywords can be some meaningful English words and are easy
to remember, which are called mnemonics. Mnemonic has long and short types. The short are
the abbreviation of the long. Use specific character to separate keywords, data and sentences.

Introduction to the SCPI Language

Rule to format mnemonics
1) If the letter number of an English word is less than or equal to 4, then the word itself can be
the mnemonic.(such as “Free” can be “FREE”);
2) If the letter number of an English word exceeds 4, then the first four letters will be the
mnemonic.(such as “Frequency” can be “FREQ”);
3) If the forth letter is vowel, then mnemonic uses the former three letters. Vowels consists of a,
e, i, o, and u.(such as “Power” can be “POW”);
4) If it is not a word but a sentence, then use the first letters of the former words and the whole
of the last word. (such as “Input Voltage “ can be “IVOLtage”)
Usage of symbols
1) Space
The space is used to separate command and parameter.
2) Colon:
If the colon is in front of the first character, it means the following is Root Command. When the
colon is set between two keywords, then it means moving from the current level to the next level.
3) *asterisk
The commands start with asterisk are named Common Command, which is used to execute
IEEE488.2 common commands.
4) Braces{}
The parameters enclosed in the braces are optional and are usually separated by the vertical bar

Introduction to the SCPI Language

"|". When using this command, one of the parameters must be selected.
5) Vertical Bar |
The vertical bar is used to separate multiple parameters and one of the parameters must be
selected when using the command.
6) Triangle Brackets < >
The parameter enclosed in the triangle brackets must be replaced by an effective value.
Parameter Type
1) Value
The command required to use value type parameter. It’s compatible with all the common
decimal display terms including optional symbol, decimal point, scientific notation and etc.
Specific value such as MIN, MAX and DEF are available.
VOLTage:{AC|DC}:RANGe {<range>|MINimum|MAXimum}
2) Discrete
The parameter should be one of the values listed. For example,
TEMPerature:RTD:UNIT {C|F|K}
3) Integer
Unless otherwise noted, the parameter can be any integer (NR1 format) within the effective value
range. Note that, do not set the parameter to a decimal, otherwise errors will occur.
4) Bool

Introduction to the SCPI Language
4
The parameter could be "OFF", "ON", for example,
TEMPerature:RTD:NULL {OFF|ON}
Command Abbreviation
Each SCPI command can be written mixed with uppercase and lowercase according to the syntax
rules, and the capital letter part is just the abbreviation of the command. If abbreviation is used,
all the capital letters in the command must be written completely. For parameters with units,
please refer to the detail parameter specifications in the sub-system.

IEEE488.2 Common Commands
6
IEEE488.2 Common Commands
*CLS
Clear all the event registers in the register set and clear the error queue.
*IDN
Return the IDcharacter string of the instrument
Description
The query returns the ID character string of the instrument.
Return Format
brand,<model>,<serial number>,X.XX.XX,{1|2}
<model>：the model number of the instrument
<serial number>：the serial number of the instrument
X.XX.XX：the software version of the instrument.
{1|2} :1(4095)2(4096)

IEEE488.2 Common Commands
7
*OPC？
Query whether the current operation is finished.
Explanation
Note the difference between the *OPC? and *OPC commands: the latter sets the "Operation
Complete" bit (bit 0) in the standard event register to 1 after the current operation is finished.
Return Format
The query returns "1" if the current operation is finished, otherwise returns "0".
*RST
Restore the instrument to its default value.
SCPI Command List
SENSe command subsystem
SenSe subsystem configuration. The basic SenSe command is [SENSe:]FUNCtion[1|2], which can
choose main display and sub display measurement function. FUNCtion[1|2] to switch mode.
Other SenSe command only change specific mode parameter, don’t change mode, for example:
VOLT:AC:RANGE:AUTO ON command will start AC voltage mode and auto-measure, but don’t
switch to AC voltage mode.
