SCPI
SCPI was defined as an additional layer on top of the IEEE 488.2-1987 specification
"Standard Codes, Formats, Protocols, and Common Commands".The standard
specifies a common syntax, command structure, and data formats, to be used with all
instruments. It introduced generic commands (such as CONFigure and MEASure) that
could be used with any instrument. These commands are grouped into subsystems.
SCPI also defines several classes of instruments. For example, any controllable power
supply would implement the same DCPSUPPLY base functionality class. Instrument
classes specify which subsystems they implement, as well as any instrument-specific
features.
The physical hardware communications link is not defined by SCPI. While it was
originally created for the IEEE-488.1 (GPIB) bus, SCPI can also be used with RS-232,
RS-422, Ethernet, USB, VXIbus, HiSLIP, etc.
SCPI commands are ASCII textual strings, which are send to the instrument over the
physical layer (e.g., IEEE-488.1). Commands are a series of one or more keywords,
many of which take parameters. In the specification, keywords are written
CONFigure: The entire keyword can be used, or it can be abbreviated to just the
uppercase portion. Responses to Query commands are typically ASCII strings.
However, for bulk data, binary formats can be used.
This section introduces the format, symbols, parameters, and abbreviations of the
SCPI command.
Instruction Format
The SCPI command is a tree-like hierarchy consisting of multiple subsystems, each
consisting of a root keyword and one or more hierarchical key words. The command
line usually begins with a colon ":"; Keywords are separated by the colon ":",
followed by optional parameter settings. The command keyword is separated by
spaces from the first parameter. The command string must end with a newline
<NL> character. Add the question mark "? " after the command line. It is
usually indicated that this feature is being queried.
Symbol Description
The following four symbols are not part of SCPI command, it cannot send with the
command. It usually used as supplementary description of command parameter.
Brace { } usually contains multiple optional parameters, it should select one
parameter when send command.
Such as DISPlay:GRID:MODE { FULL | GRID | CROSS | NONE} command
UPO 3000E&UPO2000E Series Oscilloscope Programming Manual
Page 4
UNI-T
Vertical Bar | used to separated multiple parameters, it should select one parameter
when send command.
Such as DISPlay:GRID:MODE { FULL | GRID | CROSS | NONE} command
Square Brackets [ ] the contents in square brackets (command keywords) can
omissible. If the parameter is ignoret, the instrument will set the parameter as the
default value.
Such as MEASure:NDUTy? [<source>] command, it presents current channel
Triangular Brackets < > The parameter in the brackets must be replaced with a
valid value.
Such as use DISPlay:GRID:BRIGhtness 30 form to send DISPlay:GRID:BRIGhtness
<count> command
UPO 3000E&UPO2000E Series Oscilloscope Programming Manual

Parameter Description
The parameter in this manual can divide into five types: Boolean, Integer, Real,
Discrete, ASCII string
Boolean
Parameter value can set “ON” (1) or “OFF” (0)
Such as SYSTem:LOCK {{1 | ON} | {0 | OFF}}
Integer
Parameter can take any valid integer value unless there have some other
descriptions.
Such as command: DISPlay:GRID:BRIGhtness <count> , parameter of
<count> can take integer from 0~100
UNI-T
Note: Do not set decimal as parameter, otherwise it may occur error.
Real
Parameter can take any valid integer value unless there have some other
descriptions.
Such as for command CH1, CHANnell: OFFSet <offset> , parameter of <offset>
can take integer value.
Discrete
Parameter can only take some specified numbers or characters.
Such as command DISPlay:GRID:MODE { FULL | GRID | CROSS | NONE}
parameter can only take FULL, GRID, CROSS, NONE
ASCII Character String
String parameter contain all ASCII string sets. Strings must begin and end
with paired quotes; it can use single or double quotation marks. The quotation
and delimiter can also be part of a string by typing it twice and not adding any
characters.
Such as set IP SYST:COMM:LAN:IPAD "192.168.1.10"

Shorthand Rule
All command can identify capital and small letter, if command need enter shorthand,
it should be all capital letter.
Data Return
Data return is divided into single data and batch data. The single data return is the
corresponding parameter type, in which the real return type is presents by the
scientific notation method. The part before e retains three figure behind the decimal
point, and the e part retains three figure; the batch return must be obey IEEE
488.2# string data format, ‘#’+ the length of character bits[fixed to one character]+
ASCII valid value+ valid data+ end string[‘\n’]
Such as #3123xxxxxxxxxxxxxxxxxxx\n presents 123 strings batch data return format,
‘3’ presents “123” occupies three character bits.
