|The ETH-402 is a dedicated amplifier interface for use with iWorx-brand preamplifiers that provides four channels of excitation power, gain, and noise filtration. It exhibits low system noise and offset, making it suitable for use with high resolution data acquisition systems. The ETH-402 is an ideal solution for interfacing preamplifiers, such as the iWorx NA-100 Neuroamp, and the C-ISO-104 and C-ISO-255 Bioamps to data acquisition systems.
Gain control on the ETH-402 is very straightforward. A programming resistor in the DIN-8 connector is used to set the gain. iWorx preamplifiers and transducers set the ETH-402 gain to the optimal value for a given measurement. However, this does not limit use of the ETH-402 with only iWorx preamplifiers and transducers. Many non-iWorx preamplifiers and transducers can be modified to work with the ETH-402.
The ETH-402 is packaged in a low profile aluminum enclosure that provides both durability and increased noise immunity. The device has a small foot print and multiple units are easily stacked to save bench space.
