SCPI was defined as an additional layer on top of the IEEE 488.2-1987 specification "Standard Codes, Formats, Protocols, and Common Commands". [4] The standard specifies a common syntax, command structure, and data formats, to be used with all instruments.
The “synchronous channel” carries normal bi-directional ASCII command traffic (e.g., SCPI), and synchronous GPIB meta-messages (END, triggers, etc.). The “asynchronous channel” carries GPIB-like meta-messages that need to be treated at higher priority and independent of the data path (e.g., device clear, service request).
Proposed in 2005 by Keysight [2] and VTI Instruments, [3] the LXI standard adapts the Ethernet and World Wide Web standards to test and measurement applications. [4] The standard defines how existing standards should be used in instrumentation applications to provide a consistent feel and ensure compatibility between equipment.
VISA is an industry standard implemented by several T&M companies, such as, Anritsu, Bustec, Keysight Technologies, Kikusui, National Instruments, Rigol, Rohde & Schwarz, and Tektronix. The VISA standard [ 1 ] includes specifications for communication with resources (usually, but not always, instruments) over T&M-specific I/O interfaces such as ...
SCPI is the Standard Commands for Programmable Instruments for controlling programmable test and measurement devices. SCPI or SCPi may also refer to: Pullamí Airport (ICAO airport code), in the List of airports in Chile; Sequential Central Port Injection, in the Chevrolet 90° V6 engine
An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.
Abstract Syntax Notation One (ASN.1) is a standard and flexible notation that describes data structures for representing, encoding, transmitting, and decoding data. It provides a set of formal rules for describing the structure of objects that are independent of machine-specific encoding techniques and is a precise, formal notation that removes ambiguities.
Keysight VEE is a graphical dataflow programming software development environment from Keysight Technologies for automated test, measurement, data analysis and reporting. VEE originally stood for Visual Engineering Environment and developed by HP designated as HP VEE; it has since been officially renamed to Keysight VEE.
