Shock and Vibration

The ruggedized (-D version) of the modules are designed to withstand elevated levels of shock and vibration to be
able to operate in harsh environments. The ruggedized modules have been successfully tested to the following
conditions:

Non operating random vibration:
Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis)
and up to 50Grms (Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total
of 90 minutes.

Operating shock to 40G per Mil Std. 810F, Method 516.4 Procedure I:
The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude
of the shock impulse characteristics as follows:

All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes.

Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock
magnitude of 40G was utilized. The operational units were subjected to three shocks in each direction along three
axes for a total of eighteen shocks.

Operating vibration per Mil Std 810F, Method 514.5 Procedure I:

The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810F,
Method 514.5, and Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 4 and Table 5
for all axes. Full compliance with performance specifications was required during the performance test. No damage
was allowed to the module and full compliance to performance specifications was required when the endurance
environment was removed. The module was tested per MIL-STD-810, Method 514.5, Procedure I, for functional
(performance) and endurance random vibration using the performance and endurance levels shown in Table 4 and
Table 5 for all axes. The performance test has been split, with one half accomplished before the endurance test and
one half after the endurance test (in each axis). The duration of the performance test was at least 16 minutes total
per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours
minimum per axis.
