Microelectrode AC Amplifier is a two-channel, differential amplifier equipped with Head Stage probes and is intended for extracellular recording and / or stimulating with high impedance metal microelectrodes in research and teaching applications
Extracellular neurophysiological recordings with high impedance microelectrodes can easily be done from excitable tissues such as nerve and muscle
The instrument is not intended for clinical measurements in human subjects
Special Features:
Mode Selection: This switch allows the user to select one of three Modes for each channel of the amplifier: Impedance Check (IMP), Record (REC), or Stimulate (STIM). During Impedance Check, an internal 1 kHz oscillator automatically applies a calibrated current through the electrode and the amplifier monitors the voltage in order to check impedance
Capacity: This control is used to neutralize the capacitance during electrode impedance check. In record mode, the instrument amplifies the differential input signal by an mount selected by the Gain switch. In the Stimulate mode, a stimulus is applied directly to the electrode through the Stimulus connector, and the amplifier monitors the current passing throught the electrode
Gain Selection: In the Record mode, the gain of each amplifier may be independently set by adjusting the Gain switch to x100, x1000, or x10,000
