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-2810, VT DSO-2820, VT DSO-2A10, NI DAQmx cards and so on. It consists of a dual trace oscilloscope, a real time spectrum analyzer, a signal generator and a multimeter, all of which can run 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.

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 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. (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. 5.
