- The Digital Data System (DDS) was designed to incorporate the analog-to-digital conversion process into the initial data acquisition stage and to store the data in a digital format. This conversion is done as part of the acquisition process. Consequently, the data are ready to be analyzed as soon as the test is completed. This capability permits the researcher to alter test parameters during the course of the experiment based on the information acquired in a prior portion of the test. The DDS is currently able to simultaneously acquire up to 10 channels of data. The purpose of this document is fourfold: (1) to describe the capabilities of the hardware in sufficient detail to allow the reader to determine whether the DDS is the optimum system for a particular experiment; (2) to present some of the more significant software developed to provide analyses within a short time of the completion of data acquisition; (3) to provide the reader with sample runs of major software routines to demonstrate their convenience and simple usage; and (4) a portion of the document is used to describe software which uses an FFT-box to provide a means of comparison against which the DDS can be checked.
