8424

2ch/4ch DAC, Digital I/O

Overview

The 8424 DAC card, often known as an analog output card, is ideal for situations where analog replay of signals is required. Traditionally, it is used in applications such as modal analysis or general noise and vibration analysis. Analogue output is most often used where driving a multi-post shaker is required. Captured or various generated signals can be replayed as analog voltages at optimal sample rates.

A selection of optional front panel configuration offers either four DAC outputs, two DAC outputs combined with digital I/O or digital I/O only. These options offer greater flexibility and integration with other systems.
