Multi-Instrument (Standard) with a CD, a hard key (USB dongle) and a softkey

Turn a PC into multiple virtual instruments!

1. 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 DSO, VT IEPE, VT CAMP, VT RTA, 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 from virtins.com for a 21-day fully functional FREE trial using your sound card as the ADC and DAC device.

2. Functions of Multi-Instrument (Standard)

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. AM, FM, PM Demodulation. Linear and exponential average...

Recording Mode: Record data to the hard disk continuously 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. AM, FM, PM modulation...

(4) Multimeter

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

The software also supports NI DAQmx cards such as NI USB 6009.

6. What are contained in the package to be shipped

It contains:

1. One CD for Multi-Instrument software. Note: the software is strictly copy-protected, once it is installed, it runs under 21-day fully functional (i.e. Pro version + the five add-on modules/functions) FREE trial mode. You need to use either a hardkey or a softkey (activation code) to activate the software to Multi-Instrument (Standard).

2. One USB Hardkey (dongle). Note: The hardkey is initialized to Multi-Instrument (standard). It is remotely upgradable and does not need a driver to run under Windows XP or above.

Please note that no ADC/DAC hardware contained in this item!

7. What else will be given?

In addition, one softkey (activation code) will be given within 24 hours after you register your software at our website. Note that the softkey can only unlock the software on the computer which you register with us. It is NOT a generic activation code. Internet connection is NOT required to run the software.

8. What does "one hardkey and one softkey" imply?

It implies that you can run the software on the registered computer with the softkey, and on any computer with the hardkey. In other words, you can run the software on two different computers simultaneously.

9. Software Upgrade policy

Software upgrade in the same level is always FREE. When a new version is available, you can just uninstall your current version, download and re-install the new version. The software will be activated automatically.

Software upgrade to a higher level can be purchased from virtins.com. Both the softkey and hardkey given are remotely upgradable.

10. Shipping

We ship worldwide.

The item will be shipped via express mail service within 24 hours after the payment is received. It will take normally about 5~8 days to deliver to you (e.g. USA, UK, Australia, Canada, Hong Kong, Taiwan, Japan, Korea...). In some specially cases, or special places (e.g. Italy), it may take a little longer time. The shipping and handling charge is fixed at US$30 for all places. Tracking information online will be provided 2 days after shipping. You MUST provide us your telephone number as required by the courier company to facilitate the delivery!

11. Refund Policy
