Extracellular Bio-amp anti-oscillation Unit The SI-AOSUB Anti Oscillation module operates in conjunction with the SI-BAm21-LCB module and the motor controller to actively cancel the force transducer’s natural harmonic resonance. This is critical when performing dynamic muscle contraction and release studies to ensure the integrity of the force signal from the tissue. Features l Adjustable amplitude and frequency of pulse generation to ping transducer resonant frequency l LeD amplitude meter peaks when resonant frequency is generated AMPLIFIERS, ELECTROMETERS The SI-DAM800 is a general purpose extracellular bio-amplifier module with an optional remote head stage, useful for working with metal micro electrodes. Features l High and low pass filters l multiple gain ranges from 10X to 10,000X l AC or DC coupling l Optional remote powered headstage Si-DaM800 extracellular Bio-Amplifier Si-aoSUB Anti-Oscillation module Si-DaM800 SpECiFiCationS power Input Impedance Input Leakage Current max.
