A recent article notes that newer data-acquisition systems can capture many different types of signals from a wide range of applications.

| An off-the-shelf data acquisition (DAQ) system may cost less to purchase than a custom solution, but how well will it solve your problem? For applications requiring a special mix of measurement and stimulus types or in cases where a turnkey system is desired, employing a system integrator may provide the best solution. Working with a company that has experience directly relevant to your application can save a great deal of time and money. |
An important point is ...Capturing Only the Critical Parts:
The analog signals were characterized by infrequent, transient activity. Because the customer simply digitized the inputs for a period of time, lengthy records resulted with comparatively little activity of interest.
A computer program was used to sort through the extensive data sets to find regions of interest and compare them to events found in a similar manner for other channels. The long analysis time was causing overall test times for the entire system to be excessive.
