The Micro1401-4 is a low-cost, versatile data acquisition unit. The on-board processor with high-speed memory is optimised for real-time processing, free from the constraints of the host computer operating system. Fast and accurate sampling coupled with simultaneous output offers extensive on-line experiment control.
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.
- 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
