Wireless transmitter BN-EOG2-T

EOG signal data is transmitted at a rate of 2,000 Hz, providing an extremely high resolution EOG waveform at the receiver’s output. Internal highpass and lowpass filters provide for high quality amplification of the EOG waveform, which results from the corneal-retinal electrical potential. Raw data from the pair is bandlimited from .005 Hz to 100 Hz, to provide a very high quality recording. Use to record the potentials appearing on the skin surfaces, surrounding the eyes, which are proportional to degree of eye movement and travel. The high signal to noise ratio and high time-based sampling resolution permit the pair to be used for precise oculomotor research/visual attention and visual evoked response studies. Use with a Logger or matched Receiver to emulate a “wired”connection from subject to computer, with all the benefits of a fully-wireless recording system. Due to battery operation of the wireless transmitter and close proximity to the subject’s body, common-mode rejection ratio is extremely high, considerably in excess of any typical wired EOG recording system. Accordingly, notch filters to remove mains interference (50 or 60 Hz) are typically not required. EOG data can be recorded from two independent sites, typically above and below an eye and from temple to temple. Use AcqKnowledge to evaluate nystagmus, saccadic eye movements and vestibular function. Using AcqKnowledge, wide bandwidth EOG data can be filtered to specific frequency ranges to accommodate high quality EOG signal identification even in the presence of extensive subject motion.
