- The measuring process can be followed in “real time” on the screen, can be interrupted and resumed at any time and can be continued again. Likewise, the time function of the excitation signal and the measurement signal is visible in real time.
- The measuring range is freely selectable between 0 Hz and 20,000 Hz.
- Excitation is possible, for example, with a sinusoidal sweep of any duration (more than 24 hours long if you wish) and any start and stop frequency
- Logarithmic or linear excitation, and logarithmic or linear axis scaling.
VIAS can graphically display all complex parts of the measured data: Magnitude, phase, real part, imaginary part, negative imaginary part, and negative real part. With VIAS you can calculate the transfer function of an instrument. VIAS provides a plenty of functions for processing and error correction of the data.
Furthermore, besides the Mapes Riordan simulation model used by BIAS, it offers 10 additional models ranging from Plane Waves to Spherical Waves to Multimodal Waves and selectable integrated material properties.
VIAS calculates the sound for each measured instrument assuming a fictitious excitation spectrum (several types are available for selection) and displays it in 3-dimensional graphs. Of course, sounds can also be played back via the PC. This allows objective sound comparisons between measured instruments.
Data measured or simulated with VIAS can be stored directly in the BIAS database or as a VIAS file.
Accelerometers and an impulse hammer can be used to measure stringed instruments (admittance measurement) and also to record data for modal analysis.
