Digital Performance The DS8000 represents a quantum leap in the performance of the research stimulator, and is the most advanced stimulator on the market. With a built-in computer, the entire waveform is generated digitally with precision timing. The DS8000 can generate stimulating wave patterns of a complexity unmatched by any other instrument on the market. A built in digital oscilloscope allows the user to preview waveforms on the LCD. An Ethernet connection allows the user to transfer custom waveforms and upgrade the software using TCP/IP protocol via remote access.
Output, Inputs and Waveforms The DS8000 has 8 analog outputs, 8 TTL outputs and 8 combined analog or TTL outputs. Each combined output can be comprised of a combination of any 1 to 8 channels. Eight independent internal timers and either independent external triggers are offered. The built-in waveforms include unipolar, bipolar and paired pulse, as well as step, sine, ramp and custom. A unique feature of the DS8000 is the capability to stimulate with a waveform that is identical or similar to real biopotential wave patterns associated with ECG, EEG or action potentials.
Single Board Computer Although it may be argued that some functions of the DS8000 can be implemented on a standard PC, it is important to recognise that the inherent design of a PC operating system makes the accurate delivery of precision pulse protocols impossible - they are simply not designed to generate highly accurate timing. The DS8000 platform is based on a powerfuly single board computer that is fully dedicated to the temporal accuracy and precision required in current biological and neurological research.
