RTX6001 Remote /Local Control

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.

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.
