V-Amp
Overview
V-Amp: High performance on demand
Versatility is the most distinctive feature of the BrainVision V-Amp. Favorably priced, the V-Amp is a valuable addition even for well-equipped laboratories. The V-Amp records a great variety of signals such as EEG, EOG, ECG, EMG and the full range of evoked potentials, including brainstem potentials.
Sensors for peripheral signals like GSR, blood flow, temperature interface easily with the V-Amp auxiliary ports. Compact like a multimeter and powered by an USB port, the V-Amp provides outstanding features: On board TFT-display, software controlled AC/DC-coupling, impedance measurement, bipolar as well as fully galvanically isolated auxiliary channels and an 8+1 bit trigger port.
