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.
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
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
