hardware activated license 1. Introduction Multi-Instrument is a powerful multi-function virtual instrument
software. It is a professional tool for time, frequency and
time-frequency domain analyses. 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.

The Dedicated Hardware Support add-on module is intended for
seamless integration with some third-party hardware devices. The
following third-party hardware devices are under this category:
•
RTX6001 Audio Analyzer Note that without this add-on module, RTX6001
will work as a sound card only and is still supported by
Multi-Instrument’s generic sound card drivers. With this add-on module,
the input and output data will be scaled properly by the software
without calibration, and RTX6001 is fully controllable from PC.
3. Module Specifications and
Features
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 to768
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.

Measurements Please refer to VIRTINS Sound Card Oscilloscope Probe
