SCPI Introduction SCPI (Standard Commands for Programmable Instrument) is a standard instruction set for programmable devices under IEEE 488.2. SCPI commands are divided into two parts: IEEE 488.2 Common Commands and SCPI Instrument Specific Control Commands. Common commands are commands that the instrument specified in IEEE 488.2 must support. Its syntax and semantics follow IEEE 488.2. Common commands are independent from the measurement and are used to control reset, self-test and status inspection.
The frequency and magnitude of {, , } in the command [:SENSe]:CORRection:CSET :DATA , {, , } can be omitted, or to set one or more pairs of frequency and amplitude parameters. Vertical bar | Vertical bars are used to separate multiple parameter options, one of which must be selected when sending commands. E.g, In DISPlay:MENU:STATe OFF | ON | 0 | 1 command, the parameters that can be selected are "OFF", "ON", "0" or "1".
Integers, for example, 0, 2, 30, -5 (5) NR2 numeric Decimal numbers, for example, 0.6, 3.1415926, -2.6 (6) NR3 numeric Floating point numbers, for example, 3.1415E-7, -8.2E3 (7) NRf numeric Flexible decimal number that may be type NR1, NR2 or NR3 See NR1, NR2, and NR3 examples (8) string Alphanumeric characters (must be within quotation marks) "Model, 123456" Command abbreviation All commands are not case sensitive, you can use all uppercase or lowercase.
SCPI Command Set In this command set, unless otherwise specified, the query function returns "N/A" (without the quotes) when the function is optional and not installed. And when the query function is not turned on or the type does not match, it returns "ERR" (without quotes). IEEE 488.2 Common Commands The IEEE standard defines some common commands for querying basic information about the instrument or performing common basic operations.
