4 Extended Use of Multi-Instrument Software
Multi-Instrument is a powerful 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 NI DAQmx cards, VT DSO units, and so on.
Furthermore, the ADC and DAC device can be chosen independently in Multi-Instrument.
For example, you can use VT DSO for data acquisition and use your computer’s sound card
for signal generation simultaneously.
You can change the ADC device via [Setting]>[ADC Device]>[Device Model]. For example
you can also use your computer’s sound card as the ADC device.
If the VT DSO unit does not contain a built-in DAC, then no signal generator function is
available within the hardware unit, except the digital signal output for probe calibration.
However, you can choose other DAC device via [Setting]>[DAC Device]>[Device Model].
For example, you can use your computer’s sound card as the DAC device and thus make full
use of the signal generator function of Multi-Instrument.
If you want to use the sound card as the ADC/DAC device, you may need to purchase the
dedicated sound card oscilloscope probe kit from Virtins Technology separately, or you may
make the connection by yourself.
