The National Instruments VB-8012 VirtualBench is an integrated benchtop instrument that combines several common laboratory functions in one device. It includes a mixed signal oscilloscope, function generator, digital multimeter, programmable DC power supply, and digital I O. The instrument is used in electronics laboratories, education, design verification, and general purpose troubleshooting where bench space and setup time matter.
Traditional benches use separate instruments for each function, which consumes space and requires separate connections and software. VirtualBench integrates these functions into one unit controlled through a host computer. Engineers and students can view and control multiple instruments from a single interface, which simplifies measurement workflows and documentation.
Integrated Instrument Functions
The oscilloscope section provides analog and digital channels for viewing waveforms and timing relationships. The function generator produces standard waveforms for stimulus. The digital multimeter measures voltage, current, resistance, and related quantities. The programmable power supply provides adjustable DC outputs, and the digital I O lines support logic level signals.
Each function has its own specifications for bandwidth, resolution, and accuracy. Engineers should review the specifications against the measurement requirement rather than assuming that integration implies equal performance to dedicated instruments.
Host Software and User Interface
VirtualBench is controlled through host software that presents the instruments in a unified interface. Users can arrange views, save screenshots, and export data. Settings can be stored and recalled, which supports repeatable laboratory exercises and test setups.
Because the instruments share one interface, correlating measurements across functions is easier. For example, a waveform captured on the oscilloscope can be compared with a multimeter reading taken at the same time.
Laboratory and Educational Use
In teaching laboratories, VirtualBench reduces the number of instruments that must be purchased, maintained, and connected. Students learn to use oscilloscope, generator, supply, and meter functions within one environment. In design verification, the integrated unit supports quick checks without assembling a full bench.
Instructors should define exercises that use the integrated functions together, since that is where the platform offers its main advantage.
Applications
The VB-8012 is suited to electronics education, prototype debugging, general purpose measurement, and design verification. It supports a range of laboratory tasks in a single instrument.
Installation and Maintenance
Installation requires connecting the instrument to a host computer and power source, and installing the required software. Probes and cables should be handled carefully and stored properly. The instrument should be placed with adequate ventilation.
Maintenance includes checking connectors, verifying instrument functions against known references, and updating software. Documentation of settings and calibration status supports reliable use.
Summary
The National Instruments VB-8012 VirtualBench integrates oscilloscope, function generator, digital multimeter, programmable power supply, and digital I O in one benchtop instrument. It supports electronics education, prototyping, and general purpose measurement with a unified software interface. The platform is a practical choice where bench space, setup time, and instrument coordination are important.
