DSA Devices
DSA stands for Dynamic Signal Acquisition, and the DSA Devices from National Instruments offer incredibly dynamic signal generation and acquisition capabilities. Modules such as the PXI-4461 and PXIe-4463 are especially useful for sound and vibration applications of PXI systems. The PCI-4452 is equipped with a “Measure” function, which is a control instrument used with Microsoft Excel. These NI DSA devices are designed to properly assess the frequency content of signals with a very high dynamic range- incorporating features such as antialiasing filters, IEPE conditioning, and software-configurable AC/DC coupling. The dynamic range of a device is measured with the formula 20 * log10(Vmax / Vmin), which is the ratio of the greatest and smallest signals that a circuit can measure given in dB.
