– VI leverages software (e.g., LabVIEW) and modular hardware to let users define their own instruments, rather than being limited by fixed-function traditional devices. 2. Which of the following best describes the fundamental difference between a traditional instrument and a virtual instrument? A) Traditional instruments are faster B) Virtual instruments have a fixed user interface (buttons/knobs), while traditional instruments are software-defined C) Traditional instruments have hardware-defined functionality, while virtual instruments are software-defined with the hardware providing acquisition/control D) Virtual instruments cannot measure real-world signals
– GPIB (General Purpose Interface Bus) is used to connect and control multiple traditional programmable instruments from a single PC controller. 9. Which of the following is a major advantage of virtual instrumentation over traditional instrumentation? A) Lower initial cost for every application B) Fixed and unchangeable functionality C) User-defined signal processing, analysis, and reporting D) Requires proprietary hardware for each measurement virtual instrumentation mcq
– In a traditional instrument, functions are fixed by the manufacturer. In a VI, the software defines the processing, analysis, and display; the hardware (DAQ) only interfaces with the real world. 3. Which software platform is most commonly associated with Virtual Instrumentation? A) MATLAB B) LabVIEW (Laboratory Virtual Instrument Engineering Workbench) C) Python with PyVISA D) C++ – VI leverages software (e
– The Front Panel is the interactive user interface (knobs, graphs, buttons). The Block Diagram is the graphical code that controls the program’s logic. 5. What is the primary role of a Data Acquisition (DAQ) board in a virtual instrumentation system? A) To amplify signals indefinitely B) To connect the computer to the internet C) To convert physical analog signals (e.g., voltage, temperature) into digital data for the computer, and vice versa D) To replace the need for any sensors A) Traditional instruments are faster B) Virtual instruments
