HiZx8 8-Channel Differential Amplifier
Catalog Number: 40-41-2
Eight channel extracellular includes sharp, adjustable high and low cutoff filters, a notch (line) filter, and gain to x100,000. Features probe which can be mounted near recording site to minimize pick-up noise.
As research investigators utilize more and more microelectrodes, the need for inexpensive multi-channel amplifiers which still offer critical performance and packaging features increases as well. This lead to the development of our HiZx8 Amplifier.
The instrument features an 8-channel differential probe which can be mounted near the preparation to reduce noise artifacts. Since many experiments involve transducers which generate high frequency interference, the system includes an extra sharp, 24dB/octave, 10KHz low pass filter in additional to the adjustable high cutoff filters. A wide gain range of 10-100,000 and built in 50 or 60Hz notch filter add additional tools to combat noise issues.
Compact, with built-in power supply, two HiZx8 Amplifiers (16 channels) can be mounted in only 7 inches (17.7cm) vertical space of a standard instrument rack.
The HiZX8 provides 8 channels of high impedance microelectrode recording amplification that feature:
