Multi-Instrument is a powerful multi-function virtual instrument software. It is a professional tool for time, frequency and time-frequency domain analysis. 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 NI DAQmx cards, VT DSOs, VT RTAs and so on. It consists of the following instruments and functions.
A complete package of Multi-Instrument software consists of Oscilloscope, Spectrum Analyzer, Signal Generator, Multimeter, Spectrum 3D Plot, Data Logger, LCR Meter, Device Test Plan, Vibrometer with full features in each of them.
The following table shows the function allocation in different editions of Multi-Instrument. Spectrum 3D Plot, Data Logger, LCR Meter, Device Test Plan, Vibrometer are add-on modules/functions and should be purchased separately. They are only available in Multi-Instrument Lite, Standard, and Pro editions, except that Vibrometer is only available in Multi-Instrument Standard and Pro.
With the Multi-Instrument softare, without any additional ADC and DAC hardware, you can turn your PC into a multi-function test and measurement instrument by using its built-in sound card as the ADC and DAC devices. The sampling rate can be up to 192 kHz and the sampling bit resolution can be up to 24 bits. The software have a wealth of features normally only found in much more expensive instruments. Generally, the sound card supplied with a PC is sufficient to allow measurements in the audio frequency range. Perfect measurement quality can be archived by using a professional grade sound card. Together with the VIRTINS Sound Card Oscilloscope Probe P601, which has three attenuation positions, the setup is able to measure a signal with a magnitude from as low as 1 µV to 24 V.
You can also integrate sensors, transducers, ADC and DAC hardware (e.g. sound cards, NI DAQmx cards, VT DSOs, VT RTAs, etc.), computers and the Multi-Instrument software together to form a professional test and measurement system.
