National Instruments 784343-01 VirtualBench

The National Instruments 784343-01 VirtualBench (VB-8034) is an all-in-one test and measurement device that integrates five essential instruments into a compact, portable solution. It features a 350 MHz mixed-signal oscilloscope with four analog channels and 34 digital channels. This offers accurate signal analysis for circuit design, debugging and validation. With a maximum sample rate of 1.5 GS/s per channel and a resolution of 8 bits, the oscilloscope provides detailed signal visualization. It supports DC and AC input coupling with a vertical sensitivity range from 5 mV/div to 5 V/div and input impedance settings of either 1 MΩ || 15 pF or 50 Ω.

This VirtualBench includes a function generator with a 125 MS/s update rate. It is capable of generating sine, square and arbitrary waveforms up to 20 MHz. It offers a 14-bit resolution that ensures precise signal generation for test applications. The device also incorporates a digital multimeter with 5½-digit resolution and supporting functions like AC/DC voltage, current, resistance and continuity testing. This instrument provides robust protection including fuses and reverse voltage protection.

The 784343-01 VirtualBench’s power supply features three programmable DC outputs: a 0 – 6 V output with a maximum current of 3 A and two 0 – 25 V outputs with a 1 A maximum current each. These outputs are isolated and offer precise control and safety when powering circuits. The system includes eight digital I/O channels that provide input or output control through software. These channels are capable of handling 5 V TTL input and 3.3 V LVTTL output with a drive strength of 4 mA. This makes it ideal for controlling external devices or performing simple logic operations.

The NI 784343-01 integrates seamlessly with both PCs and iPads and provides an intuitive software interface that displays all measurements on a single screen. The software is designed to be easily updated adding new functionalities over time. It also integrates with LabVIEW for automation and advanced test sequences. The device is equipped with both wired and wireless connectivity options including USB, Ethernet and Wi-Fi.

This VirtualBench comes with a compact design and weighs just 3.13 kg. The model is portable and convenient for engineers and technicians working in both laboratory and field environments. It combines the essential tools for testing and measurement.
