What is VirtualBench?

Publish Date: Feb 14, 2017 | 1 Ratings | 5.00 out of 5 | Print

Overview

VirtualBench plays a key role in reducing the cost and footprint of test and measurement systems by consolidating five of the most commonly used instruments into one device without compromising the performance of each instrument. Combined with a modern software experience and simple programming interface, VirtualBench creates new efficiencies for engineers interacting with benchtop test equipment or developing low-cost automated test systems. The VirtualBench hardware family currently consists of three models most easily designated by oscilloscope analog bandwidth: 100, 350, and 500 MHz. These models allow the VirtualBench family to serve a wide range of applications and price points in academic labs, hardware characterization/debug benches, and automated test systems.

4. Key Features

Unified Software Interface

The VirtualBench application requires zero installation and can load automatically via Windows Autoplay when connected through USB. The integrated view of all five instruments allows you to import/export instrument configurations for easier replication of test conditions. VirtualBench also includes software capabilities like digital phosphor density maps for displaying multiple acquisitions simultaneously, XY mode for plotting channels against one another, and hands-free smart capture for automatic data capture of repeated stable waveforms. In order to future-proof any VirtualBench investment, free software and firmware updates are provided as new features are released. These features, in addition to the consolidated interface, help engineers streamline their approach for benchtop characterization and validation.

Figure 4: Use measurement indicators to quickly characterize signals like this sine glitch. Choose to display common measurements like amplitude, max/min, RMS, period, and frequency indefinitely beneath the scope graph.


Figure 5: Simplify your measurements using intuitive configuration menus. The configured pulse width trigger reliably captures the displayed signal glitch.


Figure 6: Debug your system more easily by leveraging the built-in protocol decoder alongside the other instruments on the same time scale. The zero registered on the “DAC1” SPI line is likely the culprit of the glitch shown.

5. NI-VirtualBench Driver Software

Application Programming Interface (API)

In addition to the VirtualBench application, the NI-VirtualBench driver includes a best-in-class API that works with a variety of development options such as LabVIEW and C. The driver also provides access to help files, documentation, and online examples you can use as a starting point for your application.
