1. Introduction

This is one of the second-generation USB DSOs designed and developed by Virtins Technology. This generation of USB DSOs features Virtins Technology’s unique hardware-based DSP algorithm which enhances the performance and functionality dramatically without adding extra hardware cost. When used in conjunction with Multi-Instrument® software, the USB DSO converts any desktop, laptop, or tablet PC into a powerful oscilloscope, spectrum analyzer, multimeter, data logger, signal generator and so forth, all of which work simultaneously.

4. Introduction of Multi-Instrument (Standard)

Multi-Instrument (Standard) is a powerful PC based multi-function virtual instrument software. It supports a variety of hardware ranging from sound cards which are available in almost all computers to proprietary ADC and DAC hardware such as VT DSOs, NI DAQmx cards and so on. It consists of a dual trace oscilloscope, a real time spectrum analyzer, a signal generator and a multimeter, and can run them simultaneously. 

For a sound card based system, software triggering is supported.  It features a specially designed data acquisition approach, which is able to monitor the input signal continuously without missing any trigger event before a frame of data is collected. It has a very fast screen refresh rate (typically greater than 50 frames per second). It supports sophisticated triggering method including pre-trigger and post-trigger. Both level trigger and differential trigger are supported.  For a non sound card based system, the triggering capability depends on the hardware used. Hardware triggering is supported if the hardware used supports it.  Software triggering is supported if the hardware used supports data streaming. 

The software has a multilingual user interface, including English, French, German, Italian, Spanish, Portuguese, Russian, Simplified Chinese, Traditional Chinese, Japanese, and Korean.  It has been widely used in education, scientific research, audio engineering, electronic engineering, medical diagnosis, vibration analysis, etc.

The software can be downloaded for 21-day fully functional FREE trial using your sound card as the ADC and DAC device at: www.virtins.com/MIsetup.exe.

 

5. Functions of Multi-Instrument (Standard Version)

A comprehensive range of functions are provided in Multi-Instrument (Standard), including:

(1) Oscilloscope

Oscilloscope Mode: dual-trace waveform, waveform addition, subtraction and multiplication, Lissajous Pattern, transient signal recording, voltmeter.

Record Mode: Record data to the hard disk continously until the recording process is stopped manually or 2 gigabytes of data has been recorded, whichever  is earlier. During the recording process, acquired data will still be analyzed and displayed to keep the screen updated in real time. 

Roll Mode: Data displayed in the Oscilloscope will shift left gradually while the newly acquired data are added from the right.

(2) Spectrum Analyzer

RMS amplitude spectrum, relative amplitude spectrum, octave analysis (1/1,1/3,1/6,1/12,1/24, 1/48, 1/96), frequency compensation, frequency weighting (A,B,C,ITU-R 468), moving average smoothing, peak hold, linear average, exponential average, measurement of THD, THD+N, SNR, SINAD, Noise Level, IMD, Bandwidth, Crosstalk, Harmonics, Peaks, and Energy in user defined frequency bands, phase spectrum, auto correlation function, cross correlation function.

(3) Signal Generator

Function generation, multitone generation, arbitrary waveform generation, burst tone generation, MLS generation, DTMF generation, musical scale generation, white noise and pink noise generation, and frequency/amplitude sweep signal generation. Fade In / Fade Out of the output signal. 

(4) Multimeter

RMS, dBV, dBu, dBSPL, dB(A), dB(B), dB(C), Frequency Counter, RPM, Counter, Duty Cycle, Frequency/Voltage Converstion, Cycle RMS, Cycle Mean.  The latter seven modes involves a pulse counting process, with the counter trigger level, hysteresis, frequency dividing ratio adjustable.

 

6. License information and Function Allocation in Multi-Instrument Series

The full package of Multi-Instrument has six levels and five add-on modules/functions.

The six levels are: Sound Card Oscilloscope (listed price US$24.95), Sound Card Spectrum Analyzer (listed price US$39.95), Sound Card Signal Generator (listed price US$24.95), Multi-Instrument Lite (listed price US$49.95), Multi-Instrument Standard (listed price US$99.95), Multi-Instrument Pro (US$199.95).

The five add-on modules/functions are: Spectrum 3D Plot (listed price US$99.95), Data Logger (listed price US$99.95), LCR Meter (listed price US$99.95), Device Test Plan (US$99.95), Vibrometer (US$99.95). 

Note: The item on this auction contains one hardware bundled license of Multi-Instrument (Standard) without any add-on modules/functions. "Hardware bundled" means that the VT DSO-2810 hardware unit must be connected to the computer in order for the software to work under the licensed mode.  Otherwise the software will work in 21-day fully functional trial mode. No softkey (activation code) and hardkey (dongle) will be given under the hardware bundled license.

Please refer to http://www.virtins.com/multi-instrument.shtml for the function allocation matrix for the six levels of Multi-Instrument. 

 

7. Extended use of the Multi-Instrument Software

With the VT DSO-2810 unit connected to the computer, the Multi-Instrument software will run under the licensed mode. In Multi-Instrument, the ADC device and DAC device can be independently selected. For example, you can use the VT DSO-2810 as the ADC device and your computer's sound card as the DAC device, and they can work simultaneously. Or, you can use the sound card for both ADC and DAC. Note: the test lead (or probe) for sound card is not included in this pacakge, but you can make the connection by yourself or purchase it from us separately.
