Discrete Dwell Events at Different Amplitudes and Frequencies

This data shows a Slam Stick being excited at different frequencies and amplitudes. The data is helpful to understand the accelerometer's performance (the unit was just taped down too) but it is also helpful data for analysis with the different frequency content.

The Test

  • Slam Stick taped down
  • Frequency dwells: 10, 25, 50, 100, 200, 300, 400, 500, 1000, 2000 Hz
  • Amplitude dwells: first sweep at 1.05g, 10g, and 15g (the 10 Hz signal is 1/15 the other frequencies)
