For an optimal signal-to-noise ratio during a measurement, the number of data points is of great importance.
The RPAultra meets all requirements here: high sampling rate and instrument stiffness, state-of-the-art electronics and an optimized Fourier algorithm delivers unique results for material characterization.
The Fourier spectrum of the torque (modulus) and strain (displacement) is always analyzed and displayed; only then can material differences be made transparent in a repeatable manner.
