3.3.2 Results From Mechanical Shock Test

The results from the mechanical shock tests are shown in Figure 3-20 through Figure 3-23.

The scale for the y - axis is in Hz (Hertz) and the markers are provided for 0.5 PPM on either side of the variation in the plot for easy reference for understanding PPM variation.

The ppm variation is observed to be negligible during the mechanical shock test, with the variation at less than 0.5 ppm and the device operating normally after the test.
