Feedback: Force feedback.
Acceleration band: DC – 100 Hz standard (other options available)
Output sensitivity / Clip Level: 2 g standard
Peak / Full scale output: Three channels - ±20 V (40 V peak-to-peak) differential
Cross axis rejection: 0.001 g/g
Linearity: 0.1 % full scale Lowest spurious resonance: >450 Hz
Self-noise: < 1 ug rms
>147 dB @ 0.1 Hz
>151 dB @ 1 Hz
>146 dB for 5 Hz
Calibration controls: Independent signal & enable lines exposed on sensor connector
Mass control / locking: Remote offset zeroing
