RogaDAQ4 Front End is a high precision portable data
acquisition system. Four simultaneously sampled 24bits
resolution channels measure precisely any signals with frequencies up to 80kHz. RogaDAQ4 combined with PC or
notebook is a perfect measurement solution. It offers high
levels of precision and it is very easy to use.
Possible Applications
• PC based portable data acquisition
• Frequency analysis in the range 0 - 80kHz
• Structural analysis
• Modal analysis

Preamplification is realized with noise reduced
instrument amplifiers with extremely low distortion.
For IEPE compatible sensors a constant current
source can be activated by software.
User Software
The RogaDAQ4 front end can be operated directly out
of DasyLab version 13.0. This allows to perform complex
monitoring tasks like final checks in production lines or
monitoring of a frequency range with signaling if predefined intervals are left. And all of this without writing
a single line of code. Beside this drivers are available
for customer specific programming for .NET, ANSI C,
Visual C++ 6.0, Delphi, DasyLab, LabView, and MatLab.
