4. Sound Card Based Measurement System
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.
