DVC-4 Test Profile File Formats

The DVC-4 Digital Vibration Controller test setup and control parameters are saved in comma-delimited sequential files; the default file names are DvcFileS.* for Sine, DvcFileR.* for Random and DvcFileC.* for Classical Shock testing, where * is a user chosen 3-character extension such as a number from 001 to 999 or combination like B08, etc. Any text editor such as Windows Notepad can be used to open and review or modify the files.

The file consists of a 64 by 7 array plus 3 text strings at the end; each line of the array has 6 numbers followed by a comment text string. The numbers represent a Setup parameter, Frequency, Mode, Level, Limit, and Alarm. The Setup numbers reflect all of the menu selections and vary some between the three programs; a complete listing of them is given in the table below. The 3 text strings at the end are the test title, accelerometer model, and accelerometer serial number.
