The mini shaker table from Marschall Acoustics Instruments is perfect for the smaller geophysical contractor, instrumentation laboratory, or educational institution needing to test and calibrate geophone elements and accelermeters.
Economically priced, yet it has harmonic distortion figures better than many full-sized devices, -40 dB or better (-60 dB typical).
Frequency response depends on mass loading but is typically from a few Hz to over a kHz.
Larger models are available. With or without precision solid-state accelerometer and/or particle velocity sensors.
