Ex/Im(export/import) allows the current channel list to be saved to a file or a
previously saved list to be opened and applied. This allows the current settings to
be saved and applied to future tests. Unit is a shortcut to the DSA Engineering
Units section of the EDM Settings dialog, allowing the global engineering units to
be set. The remainder of the tool bar is used for library synchronization (See
“Using Libraries” below). The channel list shows a number of settings for each
channel:
Creating FFT Tests
EDM executes a created or recalled test project. A test project consists of an input
and output configuration, analysis parameters, and acquired data. A new test is
created by selecting New Test in the Test menu. This opens the New Test Wizard.

Select the type of test on the first page. Dynamic Signal Analyzer (DSA) mode is
used for data acquisition and analysis. The most general of these is FFT Spectral
Analysis (selected here) which will be employed for general vibration analysis,
control system investigations, analog circuit studies and modal analysis among
others. When required, DSA can provide various types of stimulation signals (up
to 2 per Spider-80X module) including random noise, sinewave and swept sine.
