samples which contain this amount of error. The RMS
error (or standard error) is the error value at which
68.2% of samples (one standard deviation) have an
error lower than the RMS value.
Frequency roll off data was taken by exciting the Slam
Stick at a constant amplitude (1 gee in this case) over
a range of frequencies from 10 Hz to 3200 Hz. The
measured vibration amplitude from the Slam Stick was
then plotted versus frequency. Note that the roll off is

severe after ~240 Hz. Different devices performed
differently after this frequency and amplitude data
should not be trusted when above this frequency.
Frequency data is not impacted by this roll-off. For
example if a vibration source was providing a 3 gee
amplitude at 500 Hz, the Slam Stick would properly
provide the relevant frequency information, however
the gee level would be inaccurate, most likely providing
a lower than 3 gee amplitude reading.
