The final vibe test was done on May 27th, 2022 at Element in Longmont, Colorado, The assembled spacecraft was inserted into a test deployer (provided by the launch provider), fixed to a vibe plate, and attached to a vibration test machine, shown in the figure below.
The objective of this vibe test was to satisfy a general space vehicle vibration test requirements for CIRBE: one ¼g sine sweep (20 – 2000 Hz) along each axis, followed by a random vibe test of NASA acceptance levels (10.1 Grms) along the same axis, and then another round of sine sweep (to see any unexpected difference between the two sine sweeps). Then the same set of vibe tests is done along the other two axes.
