Digital Recording System

This powerful, user friendly 4-channel digital data acquisition system utilizes the versatile Models P122 AC/DC and P511 AC Amplifiers for signal conditioning with the analog outputs connected to PolyVIEW® for display and analysis. The P122 is a high gain, low noise, stabilized DC amplifier that interfaces directly with the transducers illustrated for blood pressure, isometric force, peripheral pulse recordings and many more. The P511 amplifier features a wide range of amplification along with low and high pass filtering for recordings of EEG, EMG, ECG and nerve activity. Grass transducers for pressure, force, peripheral pulse and respiration rate, plus a set of reusable electrodes complete the package.

The optional Model SD9 Stimulator expands the system capabilities by providing muscle and nerve stimulation.

PolyVIEW, the Grass digital data acquisition package, is a natural companion for the P511 and P122. This Windows®-based application connects directly to the P511 and P122 analog outputs to provide turn-key functionality, scrolling display, waveform cursor measurements, real-time annotation, variable sample rates and powerful analysis functions. PolyVIEW offers up to 8 channels of recording capabilities and a powerful digital oscilloscope function with 20 kHz maximum digitization rate/channel. Acquire EEG, EMG, ECG, pressures, force and many other physiological data signals. Derive heart rate, integrated EMG, respiration rate, dP/dT, using PolyVIEW DSP functions in real time or post acquisition.
