Model 1700 Differential AC Amplifier The Model 1700 Differential AC Amplifier has been designed for research or teaching Four independent amplifiers in one applications which require extracellular neurophysiological recording from excitable instrument tissue, such as nerve, muscle (EMG), EEG, EKG, and ERG recordings. The instrument No Headstage required contains four independent, isolated amplifiers in a single enclosure allowing the researcher to record several signals simultaneously. Combining four channels in one Three gain settings instrument significantly reduces equipment costs while providing a more convenient research environment. Adjustable Low-Pass and High-Pass filters Each channel in the Model 1700 consists of an high-gain, low-noise differential amplifier Notch filter for power line frequency stage followed by high-pass, low-pass, and notch filters. A stimulator input is also Low noise integrated into each channel to allow for recording or stimulating through the same electrode. Simply connect your stimulation signal source to the input and set the MODE High input impedance switch to STIM; this eliminates the need to disconnect the electrode inputs from the amplifier during stimulation. Four 1-meter-long input cables are included with the High common-mode rejection amplifier. These cables can be extended up to a total length of 4 meters for an additional Low input bias current fee. Driven cable shield provides reduced The Model 1700 Differential AC Amplifier is designed for use with low impedance (<1.5 capacitance megohm) electrodes, and is therefore suitable for use with suction, nerve cuff, hook, surface, and simple metal electrodes. A-M Systems recommends the use of a headstage Custom gain and filter settings available probe (preamplifier) for use with higher impedance electrodes (see Application notes on reverse for additional information). Includes Four one-meter long input cables Includes rack mount hardware Common applications for the Model 1700 Differential AC Amplifier include, but are not limited to: 3-year warranty Multiple-Unit Recordings Evoked Potentials EEG / EMG / EKG / ERG recordings Long-term Potentiation The Model 1700 Differential AC Amplifier is designed for research grade recording quality, with a straightforward interface that also makes it ideal for teaching applications. Model 1700 Differential AC Amplifier While the Model 1700 Differential AC Amplifier was designed to record using low-impedance electrodes, many Application researchers have requested headstage probes that could be mated to one or more channels of the Model 1700 for Notes: Recording with measurements using electrodes with impedances greater than 1.5 megohms. A-M Systems can modify one, two, high-impedance three, or all four channels to work with one of our headstage probes (pictured below). Following the modification, electrodes the overall gain of the Model 1700 is not altered; however, the impedance mismatch and filtering often produced by a high impedance electrode recording configuration is eliminated.
