Chapter 1 SCPI

SCPI（Standard Commands for Programmable Instruments is a standardized instrument programming language that builds on existing standards IEEE 488.1 and IEEE 488.2 and follows the floating point rules of IEEE 754 standard,  ISO 646 message exchange 7-bit encoding notation (equivalent to ASCII programming) and many other standards.
This section introduces the format, symbols, parameters, and abbreviations of the SCPI command.

Instruction Format
Command is consisting of a keyword, separator, parameter domain and end mark. Take the following command as an example.
:VOLTage:RANGe 150
Voltage, Ranged is keyword, “:” and blank is separator, “150” is parameter (some commands have multiple parameters and separated by ”,”), the line separator or carriage return after the command is the end mark.For the convenience of description, the following conventions are adopted for subsequent symbols.

• Square Brackets “[ ]”
  The contents in square brackets (command keywords) can be omitted.

• Braces “{ }”
  It represents the parameter in command string.

• Angle Braces “< >”
  The parameter enclosed in the angle brackets must be a numerical parameter.

• Vertical Bar “|”
  It is used to separate multiple parameters.

• End Mark: line separator （0x0A）or carriage return （0x0D）

Parameter Description
The data type of programming parameters include numeric, character and Boolean type. Regardless of the type, it is expressed as an ASCII. For details, see the following table.

Shorthand Rule
All the commands are case-insensitive. The commands can be all input in uppercase letters or in lowercase letters. For abbreviations, it should enter all the uppercase letters that exist in the command syntax.

3.2 Instruction Parsing
IDN?
Function Query the instrument information.
Syntax IDN?
Example *IDN?
-> UNI-T,UTE9802+,012345678,F1.02
Description
The return format of instrument information is ,,<serial number>,< firmware version>.

*RST*
Function Restore to the factory setting.
Syntax RST
Example RST
Description
Except communication configuration parameter instruction type, baud rate, address）, other configuration parameter will restore to the factory setting.
STB?*
Function Query status byte register.
Syntax STB?
Example *STB? -> 4
Description If returned value is 4, it represents the status byte register set to 00000100; it means the error queue is not empty, which also means an error has been generated.
SAV
Function Save the current setting into nonvolatile memory for next time use.
Syntax SAV
Example *SAV
:HOLD
Function Turn on/off hold mode.
Syntax :HOLD {}
:HOLD?
Example :HOLD OFF
:HOLD? -> 0
:MODE
Function Set the measurement mode of voltage/current.
Syntax :MODE {AC|ACDC|DC}
:MODE?
AC, ACDC = (RMS)；DC
Example :MODE ACDC
:MODE? -> ACDC

:VOLTage:RANGe
Function Set the voltage range.
Syntax :VOLTage:RANGe {}
:VOLTage:RANGe?
