Software Options
Kurtosis Control
Usually in random test we adopt Gaussian distribution however, Kurtosis Control allows a none-Gaussian distribution to be used. In probability theory and statistics, kurtosis is any measure of the "peakedness" of the probability distribution of a real-valued random variable. A high kurtosis distribution has a sharper peak and longer, fatter tails, while a low kurtosis distribution has a more rounded peak and shorter, thinner tails.

Notching and Limiting Control
Assign limiting/notching parameters to measurement channels, the drive output will be limited to keep the response of limiting/notching channel below the defined profile, to protect UUT from over excitation.

Multivariable Control
Multivariable control is adopting displacement control in low frequencies while acceleration control in high frequencies. This method is greatly expanding the frequency control range, VENZO vibration controller can realize continuous sine sweep test from 0.01Hz to 80 kHz, the dynamic range of controllable sine acceleration signal is up to 150dB. Especially for hydraulic shaker, join with the displacement control channel, greatly improving the low frequency control precision.
