White Paper 41
6.1.5.2 System Level Vibration
System level vibration testing consists of attaching the fully configured system the
vibration table and applying vibration for 30minutes on each of the 3 axis X, Y and Z.
Pass Criteria:
• No Visible Damage, No Displacement of components, cables or hardware.
• No Chaffing of cables contacting metal edges.
• System must operate normally after vibration testing.
Table 10 contains recommended vibration parameters for system level vibration
testing.
Table 10 Vibration Parameters
Duration 30 minutes / axis 3 Axis X, Y & Z
Frequency (HZ) Slope (dB/Octave) PSD (g2/Hz)
5–100 0 0.015
100–137 -6
137–350 0 .008
350–500 -6
500 0.0039
NOTES:
1. Frequency — denotes the vibration frequency of the table
2. Slope (dB/Octave) — The slope is the increased amplitude of the vibration as the
frequency increases per Octave or the doubling of the frequency
3. PSD (g2/Hz) — PSD is the Power Spectral Density of the vibration and g2 is the
acceleration / frequency in Hz. As the frequency goes up the Power Spectral Density or
acceleration goes down.
