IEEE 488 commands

The IEEE 488 Command Messages table lists IEEE 488 command messages that are command bytes, which you can use to configure the GPIB state. For more information about the messages table, refer to the ANSI/IEEE Standard 488.1-1987, IEEE Standard Digital Interface for Programmable Instrumentation, and ANSI/IEEE Standard 488.1-2003, IEEE Standard for. IEEE 488 is a short-range digital communications 8-bit parallel multi-master interface bus specification developed by Hewlett-Packard as HP-IB ( Hewlett-Packard Interface Bus ). It subsequently became the subject of several standards, and is generically known as GPIB ( General Purpose Interface Bus )

SCPI commands are ASCII textual strings, which are sent 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 IEEE-488 Common Commands. IEEE-488 Common commands generally control overall instrument functions, such as reset, status, and synchronization. All common commands consist of a three-letter mnemonic preceded by an asterisk: *RST *IDN? *SRE 8 Electronic Engineers approved IEEE 488-1975. IEEE 488 defined a standard electrical and mechanical interface for connectors and cables. It also defined handshaking, addressing, and general protocol for transmitting individual bytes of data to and from instruments and computers. This standard has been updated and is now IEEE 488.1-1987

The IEEE 488 bus uses levels based around the use of Schottky TTL and has a total of sixteen active lines. These lines can be organised into three categories. Eight are used for data transfer, three are used for a comprehensive form of handshaking, and the remaining five are used for general bus management, carrying status and control information IEEE 488.2 Common Commands *CLS - Clear Status Clears the instrument status byte by emptying the error queue and clearing all event registers. Also cancels any preceding *OPC command or query All common commands begin with an asterisk. The common commands are defined by IEEE 488.2. *CLS (Clear Status) *CLS. This command clears the status byte, the data questionable event register, the standard event status register, the standard operation status register and any other registers that are summarized in the status byte

It uses a specialized 24-pin cable with connectors that allow cables to be 'stacked' together. There are eight data wires; eight control wires and eight ground wires

IEEE 488.2 Message Framework IEEE 488.2 defines, at a high level, how messages and responses are constructed and sent between the computer and the instrument. These mechanisms provide a way to send the instrument multiple commands or queries and describes how responses to multiple queries should be separated GPIB commands are used to manage the GPIB interface system. They include commands such as untalk (UNT), which commands all GPIB devices to stop sourcing data bytes. The IEEE 488 standard also refers to GPIB command bytes as multiline interface messages. The IEEE 488 multiline interface messages are shown in the following table IEEE-488 INTERFACE BUS (HP-IB/GP-IB) In the early 1970's, Hewlett-Packard came out with a standard bus (HP-IB) to help support their own laboratory measur ement equipment product lines, which later was adopted by the IEEE in 1975. This is known as the IEEE Std . 488-1975 . The IEEE-488 Interface Bus (HP-IB) or general purpose interface bus (GP.

IEEE 488.2 and SCPI The SCPI and IEEE 488.2 standards addressed the limitations and ambiguities of the original IEEE 488 standard. IEEE 488.2 makes it possible to design more compatible and productive test systems. SCPI simplifies the programming task by defining a single comprehensive command set for programmable instru-mentation, regardless. A set of codes and formats to be used by devices connected via the IEEE 488.1 bus is specified. This standard also defines communication protocols that are necessary to effect application-independent and device-dependent message exchanges, and further defines common commands and characteristics useful in instrument system applications

The IEEE-488 bus also has a number of uniline commands that are carried on a single bus management line. For example, the Interface Clear (IFC) line, when asserted, sends the Interface Clear command to every bus device, causing each to reset its IEEE-488 bus interface IEEE-488 Programming Guide Model 194A High Speed Voltmeter Ql.987, Keithley Instruments, Inc.

Hi, We have recently acquired a Keithley 236 SMU along with a PC with some software for running DC sweeps (software is Test Point which is not longer supported). The PC communicates with the 236 using IEEE-488 and the Test Point software (scripts for running the routines were available from the previous user - who, of course, is longer around and cannot be contacted) uses the IEEE-488 commands. IEEE Standard Codes, Formats, Protocols, and Common Commands for Use With IEEE Std 488.1-1987, IEEE Standard Digital Interface for Programmable Instrumentation, Institute of Electrical and Electronics Engineers, 1992, ISBN 1-55937-238-9, IEEE Std 488.2-199 The SCPI Specification expands the IEEE 488.2 common command set by defining a single, comprehensive command set suitable for all instruments.
