Virtual instrumentation is the use of customizable software and modular measurement hardware to create user-defined measurement systems.. Traditional hardware instrumentation systems are made up of fixed hardware components, such as digital multimeters and oscilloscopes that are completely specific to their stimulus, analysis, or measurement function.
LabVIEW programs are collections of one or more virtual instruments (VIs). Each VI has three components, a front panel, back panel, and connector panel, all composed of nodes and wires represented graphically to the user. The front panel is built using controls and indicators. Controls are inputs, they allow a user to supply information to the VI.
Virtual instrument software architecture (VISA) is a widely used application programming interface (API) in the test and measurement (T&M) industry for communicating with instruments from a computer. VISA is an industry standard implemented by several T&M companies, such as, Anritsu , Bustec , Keysight Technologies , Kikusui, National ...
LabWindows/CVI (CVI is short for C for Virtual Instrumentation) is an ANSI C programming environment for test and measurement developed by National Instruments. The program was originally released as LabWindows for DOS in 1987, but was soon revisioned (and renamed) for the Microsoft Windows platform. The current version of LabWindows/CVI ...
International Conference on Remote Engineering and Virtual Instrumentation (REV) is an annual IAOE conference. REV is an annual conference covering topics on online & remote engineering, virtual instrumentation and applications. Like other conferences, REV offers various tracks and simultaneous sessions, tutorials and workshops.
An instrument driver, in the context of test and measurement (T&M) application development, is a set of software routines that simplifies remote instrument control. Instrument drivers are specified by the IVI Foundation [ 1 ] and define an I/O abstraction layer using the virtual instrument software architecture (VISA).
In addition to the hardware bus to control an instrument, software for the PC is also needed. Virtual Instrument Software Architecture, or VISA, was developed by the VME eXtensions for Instrumentation (VXI) plug and play Systems Alliance as a specification for I/O software. VISA was a step toward industry-wide software compatibility.
Keithley Instruments Series 4200 CVU. Automatic test equipment or automated test equipment (ATE) is any apparatus that performs tests on a device, known as the device under test (DUT), equipment under test (EUT) or unit under test (UUT), using automation to quickly perform measurements and evaluate the test results.
