Fast data acquisition and analysis

The Micro4 records waveform data, digital (event) and marker information and can simultaneously generate waveform and digital outputs in real-time for multi-tasking experimental control.  It features high-speed waveform capture at rates up to 1 MHz with 16-bit resolution.  The 32-bit RISC processor allows complex on-line analysis while freeing time for the host computer to perform other tasks, such as data manipulation and further analysis.

Features:

• 4 channels of 16-bit waveform input on base unit
• Event channels (time stamp) expansion
• Software-selectable ±5 V or ±10 V input and output ranges
• Synchronisation with other CED 1401s for large numbers of channels, all accurately timed
• USB 2.0 high-speed connection
• Firmware upgrades via CED website

CED application software

The CED Spike2 and Signal applications customize the system for use in a wide range of research areas.  Advanced software features such as on-line spike sorting in Spike2 and fast sweep modes in Signal are enhanced when using the Micro4.  Applications include

• Tetrode and n-trode recording
• Single and multi-unit spike processing
• Evoked response, TMS and rTMS
• In-vivo and in-vitro studies
• Gastro-intestinal studies
• Cardiovascular studies
• Tremor analysis
• ECG, EEG, EMG and EOG
• Patch and Voltage clamp
• Sports physiology
• LTP, LTD capture and analysis

Spike2 - continuous data acquisition and analysis

Signal - sweep-based data capture and analysis
