BMA-200 AC/DC Bioamplifier
-
The BMA-200 is a low-noise, portable, battery operated amplifier for EEG, ECG, EMG, and other extracellular applications. The BMA-200 features a wide gain range, sharp cutoff bandpass filters, an AC calibrator, and a built-in audio amplifier and speaker for monitoring the signal.
Stimulus delivery to the electrodes is accomplished by a front-panel switch, or via an external logic signal. True DC response is switch-selectable, with a variable DC offset control.
Low-power circuitry contributes to long operating time between charges, or the unit can be operated continuously with the included AC adapter. It can be used as a stable DC amplifier, and includes adjustable DC input offset controls.
