震荡中的流变测量无论在应力还是应变通常都会形成强烈的信号。随着材料复杂度的增加，在样本测试中更加需要能够覆盖广泛范围的样品弹性模量（个和应力及应变）。对于动态范围由于106的，必须消除随机噪声和系统误差修正，以确保准确的结果。高速数据采集与灵活的相关技术结合，以提高低端性能流变仪。
Rheological measurements made in oscillation in general operate on strong signals, both stress and strain. With increasing complexity of materials, the need exists to cover wide ranges in sample modulus (and hence stress and strain) during a single measurement. For dynamic ranges better than 106, random noise has to be eliminated and systematic errors corrected in order to insure accurate results. Fast data acquisition combined with a flexible correlation technique is required to improve the low end performance of an oscillatory rheometer. The harmonic analysis of large strain amplitude oscillation tests is becoming a very useful technique to characterize subtle differences in materials’ structure. A fast data acquisition is a must for the determination of magnitude and phase of the higher harmonic response in a non linear oscillation test. UV curable adhesives and coatings change from a low viscosity fluid to an elastic solid within seconds. Fast data sampling associated with a flexible window correlation method can provide up to 100 data points per second – thus allowing an accurate monitoring of rapid changing processes.
