CAN-EngineTM

A 16-bit parallel ADC (AD7655, 0-5V) supports ultra high-speed (1 MHz conversion rate) analog signal acquisition. The AD7655 contains two low noise, high bandwidth track-and-hold amplifiers that allow simultaneous sampling on two channels. Each track-and hold amplifier has a multiplexer in front to provide a total of 4 channels analog inputs. The 16-bit parallel ADC requires only two CPU I/O operations (one start, one read) to complete a 16-bit ADC reading. With on-board precision 2.5V reference, the ADC accepts 0-5V analog inputs at 16-bit resolution of 0-65,535.

ActiveTwo

BioSemi, Amsterdam

The  system sets new standards for multi channel, high resolution biopotential measurement systems for research applications. The system is a further development of our successful ActiveOne system, the first commercially available system with active electrodes. Advances in technology have allowed us to significantly increase the number of channels, digital resolution, input range, and sample rate, without any increase in size, power-consumption or costs. Second generation active electrodes are smaller in size with less cable weight, while offering even better specs in terms of low-frequency noise and input impedance. The new system confirms the solid lead that BioSemi has build over competing designs during the last years.

MEA Workstation

PLEXON Neurotechnology Research Systems

A complete system for recording and analyzing up to 64 channels of microelectrode arrays (MEAs). The MEA Workstation uses the MEA WS suite of software programs, which computes and displays real-time statistical features of the spike waveforms in three-dimensional Principal Component Analysis (PCA) space. The recorded signals are amplified and filtered by the Plexon Preamplifier, and then sent to the ADS64 acquisition device, which provides simultaneous 16-bit sampling at 40 kHz per channel. MEA WS software then displays the spike waveforms and separates them into units that represent individual neurons.
