Through the use of Ethernet communications, the LXI Standard allows for flexible packaging, high-speed I/O, and standardized use of LAN connectivity in a broad range of commercial, industrial, aerospace, and military applications. LXI-compliant instruments offer the size and integration advantages of modular instruments without the cost and form factor constraints of card-cage architectures. These systems are based on small, modular instruments, using low-cost, open-standard LAN (Ethernet). The LXI (LXI) Standard defines the communication protocols for instrumentation and data acquisition systems using Ethernet. Modern instruments rarely use secondary addresses so this puts a 30-device limit on system size. Primary addresses limit the system to 30 devices with primary addresses.This imposes transmission problems on systems spread out in a room or on systems that require remote measurements. Cable length limits the controller-device distance to two meters per device or 20 meters total, whichever is less.

Driver fanout capacity limits the system to 14 devices plus a controller.Large systems, however, have the following limitations: The IEEE-488 bus has long been popular because it is simple to use and takes advantage of a large selection of programmable instruments and stimuli. SCPI ensures compatibility and configurability among these instruments. The IEEE 488.2 specification includes the Standard Commands for Programmable Instrumentation (SCPI), which define specific commands that each instrument class must obey. This standard was subsequently revised in 1978 (IEEE-488.1) and 1990 (IEEE-488.2).

In 1975, the IEEE published ANSI/IEEE Standard 488–1975, IEEE Standard Digital Interface for Programmable Instrumentation, which contained the electrical, mechanical, and functional specifications of an interfacing system. The introduction of digital controllers and programmable test equipment created a need for a standard, high-speed interface for communication between instruments and controllers from various vendors. The original GPIB standard was developed in the late 1960s by Hewlett-Packard to connect and control the programmable instruments the company manufactured. GPIB works best for applications in industrial settings that require a rugged connection for instrument control.

The IEEE-488 specifications standardized this bus and defined its electrical, mechanical, and functional specifications, while also defining its basic software communication rules. It is one of the most common I/O interfaces present in instruments and is designed specifically for instrument control applications. It allows daisy-chaining up to 14 instruments to a system controller using a 24-pin connector. GPIB is a digital 8-bit parallel communications interface capable of achieving data transfers of more than 8 Mbytes/s.

The General Purpose Interface Bus ( GPIB) is an IEEE-488 (a standard created by the Institute of Electrical and Electronics Engineers) standard parallel interface used for attaching sensors and programmable instruments to a computer. Industry-standard communication interfaces link signal sources with measurement instruments in “ rack-and-stack” or chassis-/mainframe-based systems, often under the control of a custom software application running on an external PC. These systems are widely employed for incoming inspection, quality assurance, and production testing of electronic devices and subassemblies. Several modular electronic instrumentation platforms are currently in common use for configuring automated electronic test and measurement systems. Generally, more advanced test gear is necessary when developing circuits and systems than is needed when doing production testing or when troubleshooting existing production units in the field. ATE often includes many of these instruments in real and simulated forms. Practical electronics engineering and assembly requires the use of many different kinds of electronic test equipment ranging from the very simple and inexpensive (such as a test light consisting of just a light bulb and a test lead) to extremely complex and sophisticated such as automatic test equipment (ATE). Use of electronic test equipment is essential to any serious work on electronics systems. In this way, the proper operation of the DUT can be proven or faults in the device can be traced.
