The Accelerometer Cable - It Can't Get
No Respect

Dr. Patrick Walter,
Abstract: The accelerometer cable can often be viewed
as the Rodney Dangerfield of shock and vibration measurements - it can’t get no respect. Yet, the measurement of valid shock and
vibration data is dependent on the cable transmitting the accelerometer output
to its subsequent signal conditioning components with fidelity. The term
fidelity, as used here, implies no unacceptable degradation of the output of
the accelerometer in terms of frequency content, signal/noise ratio, or
amplitude linearity. This paper highlights both mechanical and electrical
cable characteristics of importance in maintaining signal fidelity.
