The Direct Data Acquisition options control and acquire data from a broad range of multi-channel data acquisition hardware front-ends. From the Acquisition window, you set up the front end, acquire data, and calculate Spectra, FRFs, Coherences, etc.  Impact testing, multi-shaker testing, and acquisition of operating data are supported. ODS animation can also be done directly from this window, even during a test.

The graphical user interface includes a Structure window, where the test is set up graphically and test points & directions are indicated, and a Data Block window where measurements are accumulated during a test.
