SCPI commands to an instrument may either perform a set operation (e.g. switching a power supply on) or a query operation (e.g. reading a voltage). Queries are issued to an instrument by appending a question-mark to the end of a command. Some commands can be used for both setting and querying an instrument.
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).
Keysight Technologies, Inc. is an American company that manufactures electronics test and measurement equipment and software. The name is a blend of key and insight. [2] [4] The company was formed as a spin-off of Agilent Technologies, which inherited and rebranded the test and measurement product lines developed and produced from the late 1960s to the turn of the millennium by Hewlett-Packard ...
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 ...
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.
SCPI added standard generic commands, and a series of instrument classes with corresponding class-specific commands. SCPI mandated the IEEE 488.2 syntax, but allowed other (non-IEEE 488.1) physical transports. The IEC developed their own standards in parallel with the IEEE, with IEC 60625-1 and IEC 60625-2 (IEC 625), later replaced by IEC 60488-2.
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
Ixia was a public computer networking company operating in around 25 countries until its acquisition by Keysight Technologies Inc. in 2017. Ixia was headquartered in Calabasas, California and had approximately 1,750 employees.
