g.USBamp biosignal amplifier

g.USBamp is a high-performance and high-accuracy biosignal amplifier and acquisition/processing system. It allows investigation of brain-, heart- and muscle-activity, eye movements, respiration, galvanic skin response and many other physiological and physical parameters. Due to its technical specifications and various software options, this instrument became a standard for many different fields of research, including neuropsychology, life science, medical research and biofeedback/neurofeedback/BCI research.

g.USBamp is USB 2.0 enabled  and comes with 16 simultaneously sampled biosignal channels with 24 bits. A total of 4 independent grounds guarantee no interference between the recorded signals.

Award winning technology

The amplifier connects easily to the USB socket on your PC/notebook and can immediately be used for data recording.

Build a multi-channel system with more than 16 channels using multiple g.USBamp devices. A synchronization cable guarantees that all devices are sampling with exactly the same frequency.

The amplifier has an input range of ± 250 mV, which allows recording of DC signals without saturation.

Digital inputs and outputs allow the recording of trigger channels together with the biosignal channels to easily pass analysis results to the outside world.
A short-cut input allows connecting the amplifier inputs quickly to ground potential to protect the amplifier against overflows, which may occur in operating rooms with gamma knifes or other environments.
