This software is a versatile virtual instrument that is based on a powerful sound card. It includes essential functions such as Oscilloscope, Spectrum Analyzer, and Dynamic Signal Analyzer, as well as Frequency Counter and Signal Generator, which provides various functionality ranging from Function and Arbitrary waveform generatation to Noise and Sweep/Burst patterns.

One of the primary features of Multi-Instrument is its dual-trace waveform oscilloscope, which is capable of carrying out various complex functions such as waveform addition, subtraction, and multiplication. It also offers Lissajous Pattern generation, signal recording, and digital filtering.
The spectrum analyzer function on Multi-Instrument is also highly advanced, providing users with frequency analysis and amplitude spectrum measurement. It includes octave analysis (1/1,1/3,1/6,1/12,1/24,1/48,1/96), frequency weighting (A, B, C, ITU-R 468), peak hold, linear/exponential average, and measurement of various parameters like THD, THD+N, SNR, SINAD, Noise Level, IMD, Bandwidth, Crosstalk, peaks, harmonics, phase spectrum, auto/cross correlation, coherence function, transfer function, and impulse response. This feature also supports 60 window functions and window overlap.
The signal generator function is also highly versatile, providing support for Function/Multitone/Arbitrary waveform/Burst tone/MLS/DTMF/Musical scale/White noise/ Pink noise generation, as well as frequency/amplitude sweep and fade in/out.
Finally, Multi-Instrument also comes equipped with a frequency counter multimeter function making it one of the most comprehensive software in the market. For more detailed information, visit www.virtins.com.
